8378274572 Added support for the "d_type" member of the "dirent" structure.
If the '_DIRENT_HAVE_D_TYPE' macro is defined after "#include <dirent.h>" has been used successfully, it means that the "dirent" structure features the "d_type" member. The directory entry type values were adapted from 4.4BSD-Lite2, but not all of these are used.

e02089e28a Better handling of unbuffered mode for interactive streams
If the stream is unbuffered and turns out to be an interactive stream (e.g. stderr) then output will be made to follow the rules of line buffering to yield better readability of the output. Similar code exists with fputs(), for example.
2019-08-24 14:05:09 +02:00

2bcfec3e60 Optimizations for better write performance.
fwrite() now tries to fill the write buffer as far is possible and will only resort to using the __putc() macros when necessary. This should improve write performance by quite a bit.

If the write buffer happens to be empty and the number of bytes to write is at least as large as the write buffer, then fwrite() will directly call write(). This should improve write performance, too.

If the file is in unbuffered mode, fwrite() now always calls write(), bypassing the write buffer altogether.

obarthel
4a01746be2 Optimizations for better write performance.
fputs() now works almost exactly like fwrite(), except that it's dealing with a NUL-terminated string.
2019-08-24 14:00:03 +02:00

914ef57844 Changed how size=0 plays out
Setting the buffer size to 0 had the effect of switching the buffering mode. This is a bad idea since it wasn't actually called for: this is what the 'bufmode' parameter is intended for. What happens now is that the default buffer size is used (BUFSIZ), which sort of follows what the BSD libc did: a zero buffer size delayed the allocation of a buffer until the first read/write access occured.

089ae11181 Improvements for better read performance.
gets() now tries to copy as much data from the read buffer as possible, and will fall back onto using the __getc() macro only if necessary. This should improve performance on long lines, or crash faster if the read buffer happens to be too short. This is probably wasted on gets(), but you never know...
2019-08-24 13:55:31 +02:00
obarthel
ae13cd77fc Optimizations for better read performance.
If the buffer mode is set to "no buffering" then fread() will always bypass the buffer and call read() instead.

If there is enough data waiting to be read from the buffer, fread() will now copy it directly, refilling the buffer as needed.

If the read buffer happens to be empty, buffering is enabled for the stream, and the number of bytes to read is at least as large as the buffer size,  then fread() will directly call read(), which should improve performance significantly.
2019-08-24 13:53:48 +02:00
obarthel
3f21e90fca Optimizations for better read performance
fgets() now copies as much data from the read buffer as possible, falling back onto the __getc() macro only as a last resort. This should help greatly when reading long lines since the overhead of calling __getc() goes away.

bc621bed9c Disable the LOG_COMMAND.
Piping will have the consequence that the exit status of the first command
will not be considered. As this is the compiling command in our case, make
will not exit with an error code even if the compiling failed.

While there are shell-specific solutions, disabling LOG_COMMAND seems to
be the most general solution.

5617c0eacf Slab allocator update
Unused slabs which get recycled are no longer reinitialized from scratch if their chunk size matches what the allocator needed. If the chunk size matches, the list of available chunks is left unchanged, and just the various counters are reset.

Added support for global __slab_purge_threshold tuning variable.

Added a short test program for the slab allocator.

d2acae7cd7 Slab allocator update
Added more consistency checking to the slab allocator, which is built if DEBUG is defined in "stdlib_slab.c".

Memory allocations are no longer guaranteed to be aligned to 64 bit word boundaries. In fact, this has not even worked reliably in the past 10 years.

Memory allocation request sizes are now rounded to multiples of 32 bit words (the size of an address pointer) instead to the size of a 64 bit word.

Reduced the memory footprint of the memory allocation management data structures by reusing the most significant bit of the memory allocation size. This allows many more allocations to fit into the 32 byte chunk slabs, but limits the maximum memory allocation size to a little less than 2 GBytes.

Added integer overflow checks to the memory management code.

Reduced the memory management overhead further. This cuts an additional 8 bytes per allocation, unless neither the slab allocator nor memory pools are available. With this reduction the slab allocator is able to use 16 byte chunks, which cover memory allocation requests of 1..8 bytes.

Fixed a bug caused by returning an allocation back to a slab which passed the wrong pointer.

0c5b88d2d3 Slab allocator changes
If the first slab in the list of slabs which share the same chunk size has no more room, it means that all other slabs following it have no room either. This speeds up the test to find a slab with free space, which can now abort and directly proceed to allocate memory for a new slab.

If an empty slab's decay count hits zero, it is moved to the front of the empty slab list to be reclaimed more quickly.

Allocations made from the slab now carry a pointer back to the slab which they are a part of. This speeds up deallocation but has the downside of making the smallest usable slab chunk size 64 bytes, which is double what used to be the minimum before.

The maximum slab size is now 2^17 bytes (= 131072). If you request a slab size larger than this, you will get slab sizes of 131072 bytes instead.

fbc8694c49 Added a slab allocator
Added a slab allocator which replaces the use of memory pools or the plain AllocMem() operations, respectively. In order to activate the slab allocator, choose a slab size (e.g. 2048 bytes or 4096 bytes) and declare a global variable like this:

   ULONG __slab_max_size = 2048;

Memory allocations smaller than the slab size will be made from "slabs", i.e. large chunks of memory of the given size. Larger allocations will be managed separately.

025b183b5a Unused slabs are getting purged after adding a new slab
If a new slab is allocated, or an empty slab is reused, the list of empty slabs is now purged, if possible. Empty slabs which cannot be immediately purged "decay" and will be collected the next time a new slab is allocated or an empty slab is reused.

If a chunk is allocated and the slab which the chunk came from is fully utilized, the slab is moved to the end of its list. This should avoid searching this slab for free space before all other slabs of the same chunk size have been tested first. Slabs with free space are always placed closer to the head of the list.

8051da3c9a Added a slab allocator
A slab-allocator can now be used as the back-end for all memory allocations by setting __slab_max_size to a value > 0. This controls the slab size used for allocations and should be a power of 2, such as 2048 or 4096 bytes.

This change still needs testing.

- The fscanf() family failed to parse and convert %f parameters correctly
  if the respective number did not begin with a digit, but a decimal
  point. Hence ".7" would not be processed, but "0.7" would.

c.lib 1.206 (24.4.2015)

- Reworked the __putc() and putc() macros to reference the 'c' input
  parameter only once, and to be free of side-effects when tinkering
  with the buffer position.

- isatty() had the __fd_lock() call in the wrong place, which could have
  led to cleanup problems later.

- The close action in the stdio, socket and termios hook code now
  also zaps the fd pointer itself after cleaning up the file descriptor
  table entry.

- Removed the remains of all the stack extension and stack overflow/underflow
  checking code. It never actually worked. The bit that does work is the stack
  usage measurement code, plus the bit that sets up the the custom stack
  according to local setting or by calling a query function.

# clib2 An ISO 'C' (1994) compliant runtime library for AmigaOS

## What is this?
This is my attempt to get Samba 2.2.x ported to the Amiga. My first Amiga port required *SAS/C* and a number of strange tricks had to be pulled to get it to support the kind of environment Samba needed. But with the introduction of Samba 2.2.x many of those tricks did not work any more, which is why I decided to attack the problem at the root, namely the runtime library.
Because it was no longer possible to build Samba with *SAS/C* on the new Amiga platform, the idea came up to move development to the GNU 'C' compiler. This turned out to be a challenge due to its somewhat underdeveloped runtime library and header files. Eventually, I decided to rewrite that library from scratch.
## What does it do?
Using *'C' - A reference manual* (4th edition) as a reference I wrote a set of header files, then proceeded to implement each single function referenced in them. With few exceptions in the area of wide character support, the result should be a feature complete implementation of the ISO 'C' (1994) runtime library. The library was subsequently updated to offer functionality defined in *ISO/IEC 9899:1999*, also known as *C99*.
Because Samba needs a few POSIX-like routines to be supported, the library functionality is complemented by a set of routines described in *Advanced programming in the Unix environment*.
This is not a portable implementation of the library in the sense that you could move it from one 'C' compiler on one operating system to another. This is an Amiga specific implementation.
The library supports floating point math, which, for the 68k platform, is limited to IEEE single and double precision or M68881 inline math. There is no support for the fast floating point (FFP) format or exclusive IEEE single precision. You either get double precision (IEEE math) or extended precision (M68881 inline math). What it is that you get is determined at compile time. Use the `IEEE_FLOATING_POINT_SUPPORT` preprocessor symbol to activate IEEE math code and the `M68881_FLOATING_POINT_SUPPORT` symbol for M68881 inline math.
For the PowerPC platform, the library uses code borrowed from <a href="http://www.netlib.org/fdlibm/">fdlibm 5.3</a>, which is a portable library of arithmetic functions developed by Sun Microsystems which, for example, is also used within the Java platform.
## What does it not do?
This library is a departure from the typical 'C' runtime environments of the past which had to run on all AmigaOS releases, down to *Kickstart 1.1*. This very library was designed to take advantage of the routines available since *Kickstart 2.04* was introduced and virtually nobody ever put to use. This helps to cut the code size, and it also helps to keep bugs out of the library by falling back onto well-tested implementations. However, the catch is that the code won't run under *Kickstart 1.3* and below. But then these operating system releases have been obsolete for more than a decade, and you can always go back to a compiler environment which supports them.
There is very little support for `amiga.lib` functionality. There is `NewList()`, `HookEntry()`, `CallHook()`, `CallHookA()`, the `DoMethod()` family, the *RexxVars* family, but that's all. If you need more, you would have to implement it yourself. Put another way, if you absolutely need functionality that is only found in `amiga.lib`, you really shouldn't need it in the first place.
## Where does the source code come from?
I originally thought that it might be helpful to piece this library together from various sources, such as the BSD libc. It turned out that this code was so 'portable' that it became much more complex than it ought to be. Also, some side-effects were present which considerably changed the behaviour of the library. For example, the BSD libc uses `bcopy()` as an alias for `memcpy()`, and unlike `memcpy()` is documented to, `bcopy()` supports overlapping copies.
Eventually, I wrote virtually all the code myself, borrowing algorithmic ideas from the BSD libc and the *Manx Aztec 'C'* runtime library. Because I don't know much about the environment *GCC* expects, I borrowed code snippets from *libnix*, which was written by Matthias Fleischer and Gunther Nikl. This in particular concerns the integer and floating point math support, the `setjmp`/`longjmp` routines and the startup code. The M68881 inline math code comes from the `<math-68881.h>` file written by Matthew Self `(self [at] bayes.arc.nasa.gov)`.
## Limitations and caveats
There is hardly any documentation on the code I wrote. In part this is due to the fact that the code itself is very simple in design. It should speak for itself. However, to make a usable runtime library you have to have a user documentation as in *man pages* or *AutoDocs*. We will eventually have to have *AutoDocs* for this library.
The exception handling in the math code is not particularly effective. For one part this is due to the fact that there is no exception handler installed by the runtime library when it starts up which could catch and process the error conditions the CPU or FPU generates. The idea was to provide for a portable runtime library with little to no assembly language involved. To make the exception handling complete, such code would be necessary.
The library currently builds under *SAS/C*, but because the 'normal' program startup code is not utilized, the base relative (A4) addressing does not work. If you are going to test it, use the `data=faronly` option to compile the library and the programs.
Different build *Makefiles* are supplied for use with *GCC*. There is a `GNUmakefile.68k` for the 68k platform and a `GNUmakefile.os4` for the AmigaOS4 PowerPC version.
### Floating point math and functions (`scanf()`, `printf()`, etc.)
The plain `libc.a`, which your software would be linked against by default, does not contain any floating point support code. This means, for example, that `printf("%f",...)` will not produce the desired output and that `scanf("%f",...)` may not read any data at all. If your program needs functions such as these or `atod()` then you must link against `libm.a` or the equivalent.
To link the floating point support code with your software, use the `-lm` compiler option.
**Careful!** The order in which you specify the libraries to link against is important here. Thus, `gcc -o test test.c -lm -lc` would correctly link the program `test` against the proper floating point math library, but `gcc -o test test.c -lc -lm` would not.
### The thread-safe library
Thread-safety does not imply that you can have multiple callers access and close the same file. There is no resource tracking to that degree yet. All that the thread-safety tries to afford you is not to get into big trouble if simultaneous and overlapping accesses to files, memory allocation and other resources are taking place.
The library code is supposed to be thread-safe if built with the `__THREAD_SAFE` preprocessor symbol defined. Note that 'thread-safe' does **not** mean 'reentrant'. Multiple callers for certain library functions are permitted, but not for all of them. For example, `mkdtemp()` is not thread-safe, and neither is `rand()` or `localtime()`. But as per *POSIX 1003.1c-1995* there are thread-safe variants of `rand()` and `localtime()` called `rand_r()`, `localtime_r()`, and others.
The use of the socket I/O functions is problematic because the underlying `bsdsocket.library` API is not supposed to be used by any process other than the one which opened it. While one TCP/IP stack (my own "Roadshow") allows you to share the library base among different processes, if so configured, it is the exception. No other TCP/IP stack available for the Amiga robustly supports a similar feature. If the TCP/IP stack supports this feature, then the global variable `__can_share_socket_library_base` will be set to a non-zero value.
Errors reported by the socket I/O functions which modify the global variables `errno` and `h_errno` may be directed to call the `__set_errno()` and `__set_h_errno()` functions instead, if the TCP/IP stack supports this feature. The global variable `__thread_safe_errno_h_errno` will be set to a non-zero value if it does.
A much more serious problem resides with the `exit()`, `abort()`, `assert()` and `raise()` functions, and how the `SIGINT` signal is processed. In the thread-safe library only the `main()` function may directly or indirectly call the `exit()` function. No child process may do so, since this would wreck its stack context, crashing it instantly; the main program would be very likely to crash, too, because `exit()` will clean up after all memory allocations and files currently in use. Functions such as `abort()` and `raise()` may call the `exit()` function indirectly. And the `raise()` function may be invoked as part of the `Control+C` checking. You should make sure that the signal handling does not affect any child processes. This can be done by replacing the `__check_abort()` function or by disabling `SIGINT` processing altogether, such as through a `signal(SIGINT,SIG_IGN)` call.
Also take care with file I/O involving the `stdin`/`stdout`/`stderr` streams; read/write operations on these streams will be mapped to the `Input()`/`Output()`/`ErrorOutput()` file handles of the process performing these operations. Since only this small set of operations is mapped, functions such as `fcntl()` or `select()` will not work on the `stdin`/`stdout`/`stderr` streams and the corresponding file descriptors `STDIN_FILENO`/`STDOUT_FILENO`/`STDERR_FILENO`. It is therefore strongly recommended to use the thread-safe library only for applications which can cope with the limitations described above.
### Using gmon (PowerPC only)
To use profiling, two steps are required. First of all, your program must be compiled with the *GCC* command line option `-pg`. This instructs the compiler to generate special profiling code in the prologue and epilogue of each function. Additionally, the program must be linked against `libprofile.a`. To do this, either manually add `-lprofile` to the linker command line, or modify the specs file as follows. Find the lines that look like this (it may actually differ slightly from your specs file, but the important thing is that the line before the line to be modified reads `lib:`):
```
lib:
--start-group -lc --end-group
```
You will have to modify this to look like this:
```
lib:
%{pg: -lprofile} --start-group -lc --end-group
```
Normally, the `specs` file is located at the compiler's installation directory. For cross-compilers, this is `/usr/local/amiga/lib/gcc/ppc-amigaos/*compiler-version*/specs`. For a native compiler, it's in `gcc:lib/gcc/ppc-amigaos/*compiler-version*/specs`. Most likely, your compiler will already have this added to it's `specs` file.
Profiling makes use of a special PowerPC facility called the *Performance Monitor*. It allows to "mark" tasks and count only during while a marked task is running. This allows performance analysis to be made independent of the actual system load. The *Performance Monitor* is available on all PowerPC models supported by AmigaOS 4 except for the *603e*, and embedded versions of the PowerPC like the *405* and *440* series. Consult the manual of the appropriate chip for more information.
### Implementation defined behaviour
#### 'C' language
##### Environment
The `main(int argc,char **argv);` function may be called with an `argc` value of 0, in which case the `argv` variable will contain a pointer to the Amiga Workbench startup message, which is of type `struct WBStartup *`, and is defined in the Amiga system header file `<workbench/startup.h>`.
##### Characters
The current locale is derived from the current Amiga operating system locale settings. The `setlocale("")` function call will choose the current Amiga operating system locale settings. Any other name passed to the `setlocale()` function, with the exception of `"C"`, which selects the 'C' locale, must be a locale name, as used by the Amiga operating system function `OpenLocale()` in `locale.library`.
##### Floating-point
The 68k version of *clib2* supports single and double precision floating point numbers, according to the *IEEE 754* standard. The software floating point number support is built upon the Amiga operating system libraries `mathieeesingbas.library`, `mathieeedoubbas.library` and `mathieeedoubtrans.library`. The hardware floating point number support uses the M68881/M68882/M68040/M68060 floating point unit instead.
The PowerPC version of *clib2* supports only double precision floating point numbers, according to the *IEEE 754* standard, because that is exactly what the PowerPC CPU supports. Single precision numbers may be implicitly converted to double precision numbers. This also means that the *C99* data type `long double` is identical to the `double` data type. Because there is no difference between these two, the library omits support for *C99* functions specifically designed to operate on `long double` data types, such as `rintl()`.
Both the 68k and the PowerPC versions of *clib2* may call software floating point support routines in order to perform double and single precision operations that go beyond simple addition and multiplication, such as `sqrt()`. These functions come from Sun Microsystems <a href="http://www.netlib.org/fdlibm/">fdlibm 5.3</a> library.
Unless your software is linked against `libm.a` no floating point functions will be available to it, possibly causing a linker error. When using the GNU 'C' compiler, you will want to add the option `-lm -lc` to the linker command line.
The exception handling is currently entirely out of control of the developer and solely subject to the rules imposed by the operating system itself.
The `fmod()` function returns the value of the `x` parameter and sets `errno` to `EDOM` if the `y` parameter value is 0.
#### Library functions
##### `NULL`
The `NULL` pointer constant is defined in the `<stddef.h>` header and will expand to `((void *)0L)` if the 'C' compiler is used. For a C++ compiler the constant will expand to `0L` instead.
##### `assert()` diagnostic messages
The diagnostic messages printed by the `assert()` function take the following form:
> `[*program name*] *file*:*line*: failed assertion "*condition*".`
where:
Label | Meaning
----- | -------
program name | Optional program name; if the program name is not yet known, then the entire text enclosed in square brackets will be omitted.
file | The value of the `__FILE__` symbol at the location of the `assert()` call.
line | The value of the `__LINE__` symbol at the location of the `assert()` call.
condition | The condition passed to the `assert()` function.
If available, the diagnostic messages will be sent to `stderr`.
If the program was launched from Workbench or if the global variable `__no_standard_io` is set to a non-zero value, then the assertion failure message will not be displayed in the shell window, but in a requester window. The diagnostic message shown in this window will take the following form:
> `Assertion of condition "*condition*" failed in file "*file*", line *line*.`
The name of the program, if it is know at that time, will be displayed in the requester window title.
##### Signal handling
Only the minimum of required signals are supported by this library. These are `SIGABRT`, `SIGFPE`, `SIGILL`, `SIGINT`, `SIGSEGV` and `SIGTERM`.
As of this writing `SIGFPE` is never called by the floating point library functions.
The `Ctrl+C` event is translated into `SIGINT`. Signal delivery may be delayed until a library function which polls for the signal examines it. This means, for example, that a runaway program caught in an infinite loop cannot be aborted by sending it a `Ctrl+C` event unless special code is added which tests for the presence of the signal and calls the `__check_abort()` function on its own accord.
Processing of the `Ctrl+C` event involves the internal `__check_abort()` function which polls for the presence of the event and which will call `raise(SIGINT);`. The `__check_abort()` function may be replaced by user code.
##### Files
No new line characters are written unless specifically requested.
Space characters in a text stream before a new line character are read in and are not discarded.
When data is read from a file, the last character does not have to be a new line character.
No `NUL` byte will be appended to data written to a binary stream.
There is no difference between text and binary streams.
Writing to a text or binary stream does not truncate the associated file. A stream may be truncated by the initial `fopen()` call if the `mode` parameter starts with the letter `w`.
The file position indicator is initially set to the end of an append mode stream.
##### `printf()` family
The `%p` conversion is the hexadecimal representation of the pointer, and it is preceded by the string `0x`.
The `%a`, `%e`, `%f`, `%g`, `%A`, `%E`, `%F` and `%G` specifiers will produce the string `inf` for infinity.
##### `scanf()` family
The input for the `%p` conversion must be a hexadecimal number, preceded by either the string `0x` or `0X`.
In the `%[` conversion a `-` (dash) character that is neither the first nor the last character in the scanset indicates that a subrange of characters should be used. Thus `%[a-d]` is equivalent to `%[abcd]`.
The period (.) is the decimal-point character. The locale specific decimal-point character is accepted as an alternative to the period (.).
##### `malloc()`, `realloc()` and `calloc()`
In the standard `libc.a` implementation any request to allocate 0 (zero) bytes will fail. A result value of `NULL` will be returned and the global `errno` variable will be set to `EINVAL`.
In the `libunix.a` implementation a request to allocate 0 (zero) bytes will result in an allocation of at least 4 bytes, which will be set to zero. Each zero length allocation will return a different memory address.
##### `rename()`
In the standard `libc.a` implementation the `rename()` function will fail if there already is a file or directory by the new name to be used.
In the `libunix.a` implementation the `rename()` function will delete any existing file or directory by the new name.
##### `remove()`
In the standard `libc.a` implementation the `remove()` function will fail if the file is protected by deletion or currently in use.
In the `libunix.a` implementation the `remove()` function will remove the file when the program exits or the file is closed.
##### `abort()`
The `abort()` function will flush all buffered files, close all the files currently open and delete temporary files.
##### `exit()` and `_Exit()`
The value passed to the `exit()` function will be passed to the Amiga operating system. The value of `EXIT_FAILURE` is equivalent to `RETURN_FAIL` as defined in the Amiga system header file `<dos/dos.h>`; this value maps to the number 20. The value of `EXIT_SUCCESS` is equivalent to `RETURN_OK` as defined in the Amiga system header file `<dos/dos.h>`; this value maps to the number 0.
The `_Exit()` function will flush all buffered files, close all the files currently open and delete temporary files.
##### `getenv()`
Environment data is retrieved from the global Amiga operating system environment storage area through the `dos.library/GetEnv()` function. Global variables are stored in files in the `ENV:` directory.
##### `system()`
If the `command` parameter is not NULL and the `system()` function returns, then the result will be equivalent to the exit code of the program invoked, or -1 if the program could not be started. This follows the behaviour of the Amiga operating system function `dos.library/System()`. A return value of 0 typically indicates successful execution and a value > 0 typically indicates failure.
##### Time
The default time zone is derived from the Amiga operating system locale settings and takes the form `GMT+*hh*` or `GMT-*hh*`, respectively, in which *hh* stands for the difference between the local time zone and Greenwich Mean Time (actually, this is not GMT but UTC).
The `clock_t` and `time_t` types are unsigned 32 bit integers. The `time_t` epoch starts with midnight January 1st, 1970.
Daylight savings time is not supported.
The reference point used by the `clock()` function is the time when the program was started.
#### Locale specific behaviour
The direction of printing is from left to right.
The period (.) is the decimal-point character.
The `strftime()` behaviour follows the Amiga operating system locale settings. If the 'C' locale is in effect, then the output generated by the `%Z` takes the form `GMT+*hh*` or `GMT-*hh*`, respectively, in which *hh* stands for the difference between the local time zone and Greenwich Mean Time (this is really UTC).
## Conventions and design issues
You will have noticed the 330+ files in this directory. This is not the best way to organize a runtime library, but at least all the bits and pieces are in plain sight. Each file stands for the one or two routines it contains. The name indicates what routine(s) that might be. Each file name is prefixed by the name of the header file in which the corresponding routine is defined. So, for example, you will find that `unistd_lchown.c` contains the definition of the `lchown()` routine, which has its prototype defined in the `<unistd.h>` header file.
Internal function and variables which need to be visible across several modules have names prefixed with two underscores, as in `__stdio_init()`.
By default all library routines follow the ISO 'C' conventions in that where implementation defined behaviour is permitted, the AmigaOS rules are followed. For example, `unlink()` will by default operate like `DeleteFile()` and `rename()` will return with an error code set if the name of the file/directory to be renamed would collide with an existing directory entry.
## The startup code
There are three program startup files provided. The most simplistic is in `startup.c` which I use for *SAS/C*. It just invokes the setup routine which eventually calls `main()` and drops straight into `exit()`.
The `ncrt0.S` file was adapted from the *libnix* startup code which sets up the base relative data area, if necessary (the `SMALL_DATA` preprocessor symbol must be defined).
The `nrcrt0.S` file was adapted from *libnix* startup code, too, and sets up the base relative data area for programs to be made resident. Note that the `geta4()` stub is missing here; it wouldn't work in a resident program anyway.
The `ncrt0.S` and `nrcrt0.S` files are considerably smaller and less complex than the *libnix* code they are based on. This is because in this library design all the more complex tasks are performed in the `stdlib_main.c` file rather than in assembly language.
## Documentation
Well, you're reading it. There isn't anything much yet. You can consult the book *'C' - A reference manual* and you could look at the
<a href="http://www.opengroup.org/onlinepubs/007904975">Open Group's Single Unix
Specification</a>.
It is recommended to browse the contents of the `include` directory. The header files contain information on library behaviour and not just data type and function prototype definitions. Specifically, the `<dos.h>` header file contains documentation about special libraries and global variables which may be used or replaced by user code.
## Legal status
Because this library is in part based upon free software it would be uncourteous not to make it free software itself. The BSD license would probably be appropriate here.
The PowerPC math library is based in part on work by Sun Microsystems:

<title>Notes on building the library</title>
<body>
<h1>Notes on building the library</h1>
<p>In order to build the library, you need a 'C' compiler (obvious, isn't it?) and
a set of header files for the networking API definitions. The networking header
files go into a directory <tt>netinclude</tt> which has to sit in the same directory as
the source code and the <tt>include</tt> directory you find in there. I'm not currently
supplying these header files here. Drop me a line, and I'll take care of that.</p>
<p>The SAS/C flavour (<tt>smakefile</tt>) should get the library built using the "large data"
model. This rules out the use of residentable programs as the startup code I'm
using is very primitive (<tt>startup.o</tt>) and doesn't tinker with A4 relative data
addressing (and how this may be set up).</p>
<p>There are two makefiles for GCC, each a different flavour. There is <tt>GNUmakefile.68k</tt>,
which will build the library for GCC on the 68k platform ("classic" Amiga). This
builds all variants of the library, for large data, small data, resident, whatever
model. It's a lot of work and I don't recommend you do this on a plain 68k machine.
It will literally (!) take hours. The other makefile flavour is for AmigaOS4 using
the PowerPC hosted GCC system (<tt>GNUmakefile.os4</tt>). This builds only the large data
version of the library, but this is usually all you need. Small data support is
currently not implemented but might follow in the future.</p>

<title>Notes on using the library with Amiga GCC (68k)</title>
<body>
<h1>Notes on using the library with Amiga GCC (68k)</h1>
<p>You can use the 68k build of clib2 with the existing Amiga 68k ports of the
GNU 'C' compiler. In order to do so, you need to modify the <tt>specs</tt> file which
controls how the compiler(s) and the linker interact, and where the linker
will look for the program startup code and library files. Also, you will need
to copy the header files, startup code and library files to the locations
where the 'C' compiler and linker expects them.</p>
<p>Please read the following description before you follow the instructions. The
changes suggested may have unexpected side-effects!</p>
<p>I have provided a working <tt>specs</tt> file with this documentation file. To switch
over an existing Amiga 68k port of GCC to use clib2, you would proceed as
follows:</p>
<ul>
<li> Locate the directory within which GCC is installed. For example, this
could be within a directory to which the name <tt>ADE:</tt>, <tt>GG:</tt> or <tt>GCC:</tt>
is assigned. For the sake of simplicity, the following notes assume
that the assignment name is <tt>GCC:</tt>
<li> Make backup copies of the following directories and files:
<ol>
<li> <tt>GCC:lib/gcc-lib/amigaos/2.95.3/specs</tt><br>
<p>(NOTE: Check the directory called <tt>GCC:lib/gcc-lib/amigaos</tt>
first; the "2.95.3" quoted above refers to the version,
revision and patch number of the GCC installed and your
version number may differ!)</p>
<li> <tt>GCC:include</tt>
<li> <tt>GCC:lib</tt>
</ol>
<li> Now you can proceed to install clib2; just copy the <tt>include</tt> and <tt>lib</tt>
directories over, like this:
<ol>
<li><kbd>Copy include GCC:include all quiet</kbd>
<li><kbd>Copy lib GCC:lib all quiet</kbd>
</ol>
<li> Finally, replace the <tt>specs</tt> file with the one provided:
<ol>
<li> <kbd>Copy specs GCC:lib/gcc-lib/amigaos/2.95.3/specs</kbd><br>
<p>(NOTE: Check the directory called <tt>GCC:lib/gcc-lib/amigaos</tt>
first; the "2.95.3" quoted above refers to the version,
revision and patch number of the GCC installed and your
version number may differ!)</p>
</ol>
</ul>
<p>Once you have completed these steps you should be able to build programs using
the 68k build of clib2 and you currently installed GCC. Note that these
changes may have the effect of rendering your C++ compiler unusable, so make
sure that you've made backup copies of all files and directories first!</p>

<title>An ISO 'C' (1994) compliant runtime library for the Amiga</title>
<body>
<h1>An ISO 'C' (1994) compliant runtime library for the Amiga</h1>
<h2>1. What is this?</h2>
<p>This is my attempt to get Samba 2.2.x ported to the Amiga. My first Amiga
port required SAS/C and a number of strange tricks had to be pulled to get
it to support the kind of environment Samba needed. But with the
introduction of Samba 2.2.x many of those tricks did not work any more,
which is why I decided to attack the problem at the root, namely the
runtime library.</p>
<p>Because it was no longer possible to build Samba with SAS/C on the new
Amiga platform, the idea came up to move development to the GNU 'C'
compiler. This turned out to be a challenge due to its somewhat
underdeveloped runtime library and header files. Eventually, I decided to
rewrite that library from scratch.</p>
<h2>2. What does it do?</h2>
<p>Using <i>'C' - A reference manual</i> (4th edition) as a reference I wrote a set of
header files, then proceeded to implement each single function referenced in
them. With few exceptions in the area of wide character support, the result
should be a feature complete implementation of the ISO 'C' (1994) runtime
library. The library was subsequently updated to offer functionality defined in
<i>ISO/IEC 9899:1999</i>, also known as <i>C99</i>.</p>
<p>Because Samba needs a few POSIX-like routines to be supported, the library
functionality is complemented by a set of routines described in <i>Advanced
programming in the Unix environent</i>.</p>
<p>This is not a portable implementation of the library in the sense that you
could move it from one 'C' compiler on one operating system to another.
This is an Amiga specific implementation.</p>
<p>The library supports floating point math, which, for the 68k platform, is
limited to IEEE single and double precision or M68881 inline math. There is no
support for the fast floating point (FFP) format or exclusive IEEE single
precision. You either get double precision (IEEE math) or extended precision
(M68881 inline math). What it is that you get is determined at compile time.
Use the <tt>IEEE_FLOATING_POINT_SUPPORT</tt> preprocessor symbol to activate IEEE math
code and the <tt>M68881_FLOATING_POINT_SUPPORT</tt> symbol for M68881 inline math.</p>
<p>For the PowerPC platform, the library uses code borrowed from <i>fdlibm 5.3</i>,
which is a portable library of arithmetic functions developed by Sun
Microsystems which, for example, is also used within the Java platform.</p>
<h2>3. What does it not do?</h2>
<p>This library is a departure from the typical 'C' runtime environments of the
past which had to run on all AmigaOS releases, down to Kickstart 1.1. This
very library was designed to take advantage of the routines available since
Kickstart 2.04 was introduced and virtually nobody ever put to use. This helps
to cut the code size, and it also helps to keep bugs out of the library by
falling back onto well-tested implementations. However, the catch is that the
code won't run under Kickstart 1.3 and below. But then these operating system
releases have been obsolete for more than a decade, and you can always go back
to a compiler environment which supports them.</p>
<p>There is very little support for <tt>amiga.lib</tt> functionality. There is <tt>NewList()</tt>,
<tt>HookEntry()</tt>, <tt>CallHook()</tt>, <tt>CallHookA()</tt>, the <tt>DoMethod()</tt> family, the RexxVars
family, but that's all. If you need more, you would have to implement it
yourself. Put another way, if you absolutely need functionality that is only
found in <tt>amiga.lib</tt>, you really shouldn't need it in the first place.</p>
<h2>4. Where does the source code come from?</h2>
<p>I originally thought that it might be helpful to piece this library together
from various sources, such as the BSD libc. It turned out that this code was so
'portable' that it became much more complex than it ought to be. Also, some
side-effects were present which considerably changed the behaviour of the
library. For example, the BSD libc uses <tt>bcopy()</tt> as an alias for <tt>memcpy()</tt>, and
unlike <tt>memcpy()</tt> is documented to, <tt>bcopy()</tt> supports overlapping copies.</p>
<p>Eventually, I wrote virtually all the code myself, borrowing algorithmic ideas
from the BSD libc and the Manx Aztec 'C' runtime library. Because I don't know
much about the environment GCC expects, I borrowed code snippets from libnix,
which was written by Matthias Fleischer and Gunther Nikl. This in particular
concerns the integer and floating point math support, the <tt>setjmp</tt>/<tt>longjmp</tt>
routines and the startup code. The M68881 inline math code comes from the
<tt>&lt;math-68881.h&gt;</tt> file written by Matthew Self <tt>(self [at] bayes&#46;arc&#46;nasa&#46;gov)</tt>.</p>
<h2>5. Limitations and caveats</h2>
<p>There is hardly any documentation on the code I wrote. In part this is due to
the fact that the code itself is very simple in design. It should speak for
itself. However, to make a usable runtime library you have to have a user
documentation as in man pages or AutoDocs. We will eventually have to have
autodocs for this library.</p>
<p>The exception handling in the math code is not particularly effective. For one
part this is due to the fact that there is no exception handler installed by
the runtime library when it starts up which could catch and process the error
conditions the CPU or FPU generates. The idea was to provide for a portable
runtime library with little to no assembly language involved. To make the
exception handling complete, such code would be necessary.</p>
<p>The library currently builds under SAS/C, but because the 'normal' program
startup code is not utilized, the base relative (A4) addressing does not work.
If you are going to test it, use the <tt>data=faronly</tt> option to compile the
library and the programs.</p>
<p>Different build makefiles are supplied for use with GCC. There is a
<tt>GNUmakefile.68k</tt> for the 68k platform and a <tt>GNUmakefile.os4</tt> for the AmigaOS4
PowerPC version.</p>
<h3>5.1 Floating point math and functions (<tt>scanf()</tt>, <tt>printf()</tt>, etc.) </h3>
<p>The plain <tt>libc.a</tt>, which your software would be linked against by default, does not contain
any floating point support code. This means, for example, that <tt>printf("%f",...)</tt> will not produce
the desired output and that <tt>scanf("%f",...)</tt> may not read any data at all. If your
program needs functions such as these or <tt>atod()</tt> then you must link against <tt>libm.a</tt> or
the equivalent.</p>
<p>To link the floating point support code with your software, use the <tt>-lm</tt> compiler option. <em>Careful!</em>
The order in which you specify the libraries to link against is important here. Thus, <tt>gcc -o test test.c -lm -lc</tt>
would correctly link the program <tt>test</tt> against the proper floating point math library, but
<tt>gcc -o test test.c -lc -lm</tt> would not.</p>
<h3>5.2 The thread-safe library</h3>
<p>Thread-safety does not imply that you can have multiple callers
access and close the same file. There is no resource tracking to that degree
yet. All that the thread-safety tries to afford you is not to get into big trouble
if simultaneous and overlapping accesses to files, memory allocation and other
resources are taking place.</p>
<p>The library code is supposed to be thread-safe if built with the <tt>__THREAD_SAFE</tt>
preprocesssor symbol defined. Note that 'thread-safe' does <em>not</em> mean
'reentrant'. Multiple callers for certain library functions are permitted, but
not for all of them. For example, <tt>mkdtemp()</tt> is not thread-safe, and neither is
<tt>rand()</tt> or <tt>localtime()</tt>. But as per <i>POSIX 1003.1c-1995</i> there are thread-safe
variants of <tt>rand()</tt> and <tt>localtime()</tt> called <tt>rand_r()</tt>, <tt>localtime_r()</tt>, and others.</p>
<p>The use of the socket I/O functions is problematic because the
underlying <tt>bsdsocket.library</tt> API is not supposed to be used by any process
other than the one which opened it. While one TCP/IP stack (my own "Roadshow") allows you
to share the library base among different processes, if so configured, it is the
exception. No other TCP/IP stack available for the Amiga robustly supports a similar
feature. If the TCP/IP stack supports this feature, then the global variable
<tt>__can_share_socket_library_base</tt> will be set to a non-zero value.</p>
<p>Errors reported by the socket I/O functions which modify the global variables
<tt>errno</tt> and <tt>h_errno</tt> may be directed to call the <tt>__set_errno()</tt>
and <tt>__set_h_errno()</tt> functions instead, if the TCP/IP stack supports this feature. The global
variable <tt>__thread_safe_errno_h_errno</tt> will be set to a non-zero value if it does.</p>
<p>A much more serious problem resides with the <tt>exit()</tt>, <tt>abort()</tt>,
<tt>assert()</tt> and <tt>raise()</tt> functions, and how the <tt>SIGINT</tt> signal is
processed. In the thread-safe library only the <tt>main()</tt> function may directly
or indirectly call the <tt>exit()</tt> function. No child process may do so, since this
would wreck its stack context, crashing it instantly; the main program would be very
likely to crash, too, because <tt>exit()</tt> will clean up after all memory allocations
and files currently in use. Functions such as <tt>abort()</tt> and <tt>raise()</tt> may
call the <tt>exit()</tt> function indirectly. And the <tt>raise()</tt> function may
be invoked as part of the <tt>Control+C</tt> checking. You should make sure that the
signal handling does not affect any child processes. This can be done by replacing the
<tt>__check_abort()</tt> function or by disabling <tt>SIGINT</tt> processing altogether,
such as through a <tt>signal(SIGINT,SIG_IGN)</tt> call.</p>
<p> Also take care with file I/O involving the <tt>stdin</tt>/<tt>stdout</tt>/<tt>stderr</tt>
streams; read/write operations on these streams will be mapped to the <tt>Input()</tt>/<tt>Output()</tt>/<tt>ErrorOutput()</tt>
file handles of the process performing these operations. Since only this small set of
operations is mapped, functions such as <tt>fcntl()</tt> or <tt>select()</tt> will not
work on the <tt>stdin</tt>/<tt>stdout</tt>/<tt>stderr</tt> streams and the corresponding
file descriptors <tt>STDIN_FILENO</tt>/<tt>STDOUT_FILENO</tt>/<tt>STDERR_FILENO</tt>.
It is therefore strongly recommended to use the thread-safe library only for applications
which can cope with the limitations described above.</p>
<h3>5.3 Using gmon (PowerPC only)</h3>
<p>To use profiling, two steps are required. First of all, your program must be compiled with
the gcc command line option <tt>-pg</tt>. This instructs the compiler to generate special
profiling code in the prologue and epilogue of each function. Additionally, the program
must be linked with <tt>libprofile.a</tt>. To do this, either manually add
<tt>-lprofile</tt> to the linker command line, or modify the specs file as follows.
Find the lines that look like this (it may actually differ silghtily from your specs file,
but the important thing is that the line before the line to be modified reads <tt>lib:</tt>):
<pre>
lib:
--start-group -lc --end-group
</pre>
You will have to modify this to look like this:
<pre>
lib:
%{pg: -lprofile} --start-group -lc --end-group
</pre>
<p>Normally, the specs file is located at the compilers installation directory. For cross-compilers,
this is <tt>/usr/local/amiga/lib/gcc/ppc-amigaos/<i>compiler-version</i>/specs</tt>. For a native compiler,
it's in <tt>gcc:lib/gcc/ppc-amigaos/<i>compiler-version</i>/specs</tt>. Most likely, your compiler will already have this added to it's specs file.</p>
<p>Profiling makes use of a special PowerPC facility called the Performance Monitor. It
allows to "mark" tasks and count only during while a marked task is running. This allows
performance analysis to be made independant of the actual system load. The Performace Monitor
is available on all PowerPC models supported by AmigaOS 4 except for the <tt>603e</tt>, and
embedded versions of the PowerPC like the <tt>405</tt> and <tt>440</tt> series. Consult the manual
of the appropriate chip for more information.</p>
<h3>5.4 Implementation defined behaviour</h3>
<h4>5.4.1. 'C' language</h4>
<h5>5.4.1.1. Environment</h5>
<p>The <tt>main(int argc,char **argv);</tt> function may be called with an <tt>argc</tt> value of 0,
in which case the <tt>argv</tt> variable will contain a pointer to the Amiga Workbench startup
message, which is of type <tt>struct WBStartup *</tt>, and is defined in the Amiga system header
file <tt>&lt;workbench/startup.h&gt;</tt>.</p>
<h5>5.4.1.2. Characters</h5>
<p>The current locale is derived from the current Amiga operating system locale settings. The
<tt>setlocale("")</tt> function call will choose the current Amiga operating system locale settings.
Any other name passed to the <tt>setlocale()</tt> function, with the exception of <tt>"C"</tt>,
which selects the 'C' locale, must be a locale name, as used by the Amiga operating system
function <tt>OpenLocale()</tt> in <tt>locale.library</tt>.</p>
<h5>5.4.1.3. Floating-point</h5>
<p>The 68k version of clib2 supports single and double precision floating point numbers,
according to the <i>IEEE 754</i> standard. The software floating point number support is built upon the Amiga
operating system libraries <tt>mathieeesingbas.library</tt>, <tt>mathieeedoubbas.library</tt>
and <tt>mathieeedoubtrans.library</tt>. The hardware floating point number support uses
the M68881/M68882/M68040/M68060 floating point unit intead.</p>
<p>The PowerPC version of clib2 supports only double precision floating point numbers, according to
the <i>IEEE 754</i> standard, because that is exactly what the PowerPC CPU supports. Single precision
numbers may be implicitly converted to double precision numbers. This also means that the <i>C99</i>
data type <tt>long double</tt> is identical to the <tt>double</tt> data type. Because there is no
difference between these two, the library omits support for <i>C99</i> functions specifically designed
to operate on <tt>long double</tt> data types, such as <tt>rintl()</tt>.</p>
<p>Both the 68k and the PowerPC versions of clib2 may call software floating point support
routines in order to perform double and single precision operations that go beyond
simple addition and multiplication, such as <tt>sqrt()</tt>. These functions come from
Sun Microsystems <i>fdlibm 5.3</i> library.</p>
<p>Unless your software is linked against <tt>libm.a</tt> no floating point functions will
be available to it, possibly causing a linker error. When using the GNU 'C' compiler, you will
want to add the option <tt>-lm -lc</tt> to the linker command line.</p>
<p>The exception handling is currently entirely out of control of the developer
and solely subject to the rules imposed by the operating system itself.</p>
<p>The <tt>fmod()</tt> function returns the value of the <tt>x</tt> parameter and
sets <tt>errno</tt> to <tt>EDOM</tt> if the <tt>y</tt> parameter value is 0.</p>
<h4>5.4.2. Library functions</h4>
<h5>5.4.2.1. <tt>NULL</tt></h5>
<p>The <tt>NULL</tt> pointer constant is defined in the <tt>&lt;stddef.h&gt;</tt> header and
will expand to <tt>((void *)0L)</tt> if the 'C' compiler is used. For a C++ compiler the constant
will expand to <tt>0L</tt> instead.</p>
<h5>5.4.2.2. <tt>assert()</tt> diagnostic messages</h5>
<p>The diagnostic messages printed by the <tt>assert()</tt> function take the following form:</p>
<blockquote><tt>[<i>program name</i>] <i>file</i>:<i>line</i>: failed assertion "<i>condition</i>".</tt></blockquote>
<p>where:</p>
<table border=0>
<tr><th align=right>program name</th><td>Optional program name; if the program name is not yet known, then the
entire text enclosed in square brackets will be omitted.</td></tr>
<tr><th align=right>file</th><td>The value of the <tt>__FILE__</tt> symbol at the location of the <tt>assert()</tt> call.</td></tr>
<tr><th align=right>line</th><td>The value of the <tt>__LINE__</tt> symbol at the location of the <tt>assert()</tt> call.</td></tr>
<tr><th align=right>condition</th><td>The condition passed to the <tt>assert()</tt> function.</td></tr>
</table>
<p>If available, the diagnostic messages will be sent to <tt>stderr</tt>.</p>
<p>If the program was launched from Workbench or if the global variable <tt>__no_standard_io</tt> is set
to a non-zero value, then the assertion failure message will not be displayed in the shell window, but
in a requester window. The diagnostic message shown in this window will take the following form:</p>
<blockquote><tt>Assertion of condition "<i>condition</i>" failed in file "<i>file</i>", line <i>line</i>.</tt></blockquote>
<p>The name of the program, if it is know at that time, will be displayed in the requester window title.</p>
<h5>5.4.2.3. Signal handling</h5>
<p>Only the minimum of required signals are supported by this library. These are <tt>SIGABRT</tt>, <tt>SIGFPE</tt>,
<tt>SIGILL</tt>, <tt>SIGINT</tt>, <tt>SIGSEGV</tt> and <tt>SIGTERM</tt>.</p>
<p>As of this writing <tt>SIGFPE</tt> is never called by the floating point library functions.</p>
<p>The <tt>Ctrl+C</tt> event is translated into <tt>SIGINT</tt>. Signal delivery may be delayed
until a library function which polls for the signal examines it. This means, for example, that
a runaway program caught in an infinite loop cannot be aborted by sending it a <tt>Ctrl+C</tt> event unless special code
is added which tests for the presence of the signal and calls the <tt>__check_abort()</tt> all on its own.</p>
<p>Processing of the <tt>Ctrl+C</tt> event involves the internal <tt>__check_abort()</tt> function which
polls for the presence of the event and which will call <tt>raise(SIGINT);</tt>. The <tt>__check_abort()</tt>
function may be replaced by user code.</p>
<h5>5.4.2.4. Files</h5>
<p>No new line characters are written unless specifically requested.</p>
<p>Space characters in a text stream before a new line character are read in and not discarded.</p>
<p>When data is read from a file, the last character does not have to be a new line character.</p>
<p>No NUL byte will be appended to data written to a binary stream.</p>
<p>There is no difference between text and binary streams.</p>
<p>Writing to a text or binary stream does not truncate the associated file. A stream may be
truncated by the initial <tt>fopen()</tt> call if the <tt>mode</tt> parameter starts with
the letter <tt>w</tt>.</p>
<p>The file position indicator is initially set to the end of an append mode stream.</p>
<h5>5.4.2.5. <tt>printf()</tt> family</h5>
<p>The <tt>%p</tt> conversion is the hexadecimal representation of the pointer, and
it is preceded by the string <tt>0x</tt>.</p>
<p>The <tt>%a</tt>, <tt>%e</tt>, <tt>%f</tt>, <tt>%g</tt>, <tt>%A</tt>,
<tt>%E</tt>, <tt>%F</tt> and <tt>%G</tt> specifiers will produce the string <tt>inf</tt>
for infinity.</p>
<h5>5.4.2.6. <tt>scanf()</tt> family</h5>
<p>The input for the <tt>%p</tt> conversion must be a hexadecimal number,
preceded by either the string <tt>0x</tt> or <tt>0X</tt>.</p>
<p>In the <tt>%[</tt> conversion a <tt>-</tt> (dash) character that is neither the
first nor the last character in the scanset indicates that a subrange of
characters should be used. Thus <tt>%[a-d]</tt> is equivalent to <tt>%[abcd]</tt>.</p>
<p>The period (.) is the decimal-point character. The locale specific decimal-point
character is accepted as an alternative to the period (.).</p>
<h5>5.4.2.7. <tt>malloc()</tt>, <tt>realloc()</tt> and <tt>calloc()</tt></h5>
<p>In the standard <tt>libc.a</tt> implementation any request to allocate
0 (zero) bytes will fail. A result value of <tt>NULL</tt> will be returned and
the global <tt>errno</tt> variable will be set to <tt>EINVAL</tt>.</p>
<p>In the <tt>libunix.a</tt> implementation a request to allocate
0 (zero) bytes will result in an allocation of at least 4 bytes, which will
be set to zero. Each zero length allocation will return a different
memory address.</p>
<h5>5.4.2.8. <tt>rename()</tt></h5>
<p>In the standard <tt>libc.a</tt> implementation the <tt>rename()</tt> function
will fail if there already is a file or directory by the new name to be used.</p>
<p>In the <tt>libunix.a</tt> implementation the <tt>rename()</tt> function will
delete any existing file or directory by the new name.</p>
<h5>5.4.2.9. <tt>remove()</tt></h5>
<p>In the standard <tt>libc.a</tt> implementation the <tt>remove()</tt> function
will fail if the file is protected by deletion or currently in use.</p>
<p>In the <tt>libunix.a</tt> implementation the <tt>remove()</tt> function
will remove the file when the program exits or the file is closed.</p>
<h5>5.4.2.10. <tt>abort()</tt></h5>
<p>The <tt>abort()</tt> function will flush all buffered files,
close all the files currently open and delete temporary files.</p>
<h5>5.4.2.11. <tt>exit()</tt> and <tt>_Exit()</tt></h5>
<p>The value passed to the <tt>exit()</tt> function will be passed to the
Amiga operating system. The value of <tt>EXIT_FAILURE</tt> is equivalent
to <tt>RETURN_FAIL</tt> as defined in the Amiga system header file
<tt>&lt;dos/dos.h&gt;</tt>; this value maps to the number 20. The value
of <tt>EXIT_SUCCESS</tt> is equivalent to <tt>RETURN_OK</tt> as defined in
the Amiga system header file <tt>&lt;dos/dos.h&gt;</tt>; this value maps to
the number 0.</p>
<p>The <tt>_Exit()</tt> function will flush all buffered files,
close all the files currently open and delete temporary files.</p>
<h5>5.4.2.12. <tt>getenv()</tt></h5>
<p>Environment data is retrieved from the global Amiga operating system environment
storage area through the <tt>dos.library/GetEnv()</tt> function. Global variables are
stored in files in the <tt>ENV:</tt> directory.</p>
<h5>5.4.2.13. <tt>system()</tt></h5>
<p>If the <tt>command</tt> parameter is not NULL and the <tt>system()</tt> function returns, then the result will
be equivalent to the exit code of the program invoked, or -1 if the program could not be started.
This follows the behaviour of the Amiga operating system function <tt>dos.library/System()</tt>.
A return value of 0 typically indicates successful execution and a value &gt; 0
typically indicates failure.</p>
<h5>5.4.2.14. Time</h5>
<p>The default time zone is derived from the Amiga operating system locale
settings and takes the form <tt>GMT+<i>hh</i></tt> or <tt>GMT-<i>hh</i></tt>,
respectively, in which <i>hh</i> stands for the difference between the local
time zone and Greenwich Mean Time.</p>
<p>The <tt>clock_t</tt> and <tt>time_t</tt> types are unsigned 32 bit integers.
The <tt>time_t</tt> epoch starts with midnight January 1st, 1970.</p>
<p>Daylight savings time is not supported.</p>
<p>The reference point used by the <tt>clock()</tt> function is the time
when the program was started.</p>
<h4>5.4.3. Locale specific behaviour</h4>
<p>The direction of printing is from left to right.</p>
<p>The period (.) is the decimal-point character.</p>
<p>The <tt>strftime()</tt> behaviour follows the Amiga operating system locale
settings. If the 'C' locale is in effect, then the output generated by the
<tt>%Z</tt> takes the form <tt>GMT+<i>hh</i></tt> or <tt>GMT-<i>hh</i></tt>,
respectively, in which <i>hh</i> stands for the difference between the local
time zone and Greenwich Mean Time.</p>
<h2>6. Conventions and design issues</h2>
<p>You will have noticed the 330+ files in this directory. This is not the best
way to organize a runtime library, but at least all the bits and pieces are in
plain sight. Each file stands for the one or two routines it contains. The
name indicates what routine(s) that might be. Each file name is prefixed by
the name of the header file in which the corresponding routine is defined. So,
for example, you will find that <tt>unistd_lchown.c</tt> contains the definition of
the <tt>lchown()</tt> routine, which has its prototype defined in the <tt>&lt;unistd.h&gt;</tt> header
file.</p>
<p>Internal function and variables which need to be visible across several
modules have names prefixed with two underscores, as in <tt>__stdio_init()</tt>.</p>
<p>By default all library routines follow the ISO 'C' conventions in that where
implementation defined behaviour is permitted, the AmigaOS rules are followed.
For example, <tt>unlink()</tt> will by default operate like <tt>DeleteFile()</tt> and <tt>rename()</tt>
will return with an error code set if the name of the file/directory to be
renamed would collide with an existing directory entry.</p>
<h2>7. The startup code</h2>
<p>There are three program startup files provided. The most simplistic is in
<tt>startup.c</tt> which I use for SAS/C. It just invokes the setup routine which
eventually calls <tt>main()</tt> and drops straight into <tt>exit()</tt>.</p>
<p>The <tt>ncrt0.S</tt> file was adapted from the libnix startup code which sets up the
base relative data area, if necessary (the <tt>SMALL_DATA</tt> preprocessor symbol must
be defined).</p>
<p>The <tt>nrcrt0.S</tt> file was adapted from libnix startup code, too, and sets up the
base relative data area for programs to be made resident. Note that the
<tt>geta4()</tt> stub is missing here; it wouldn't work in a resident program anyway.</p>
<p>The <tt>ncrt0.S</tt> and <tt>nrcrt0.S</tt> files are considerably smaller and less complex than
the libnix code they are based on. This is because in this library design all
the more complex tasks are performed in the <tt>stdlib_main.c</tt> file rather than in
assembly language.</p>
<h2>8. Documentation</h2>
<p>Well, you're reading it. There isn't anything much yet. You can consult the book
<i>'C' - A reference manual</i> and you could look at the
<a href="http://www.opengroup.org/onlinepubs/007904975">Open Group's Single Unix
Specification</a>.</p>
<p>It is recommended to browse the contents of the <tt>include</tt> directory. The
header files contain information on library behaviour and not just data type and
function prototype definitions. Specifically, the <tt>&lt;dos.h&gt;</tt> header file
contains documentation about special libraries and global variables which may be
used or replaced by user code.</p>
<h2>9. Legal status</h2>
<p>Because this library is in part based upon free software it would be
uncourteous not to make it free software itself. The BSD license would
probably be appropriate here.</p>
<p>The PowerPC math library is based in part on work by Sun Microsystems:</p>

c.lib 1.217 (10.7.2025)
- Added support for handling path names that exceed 255 characters in
the AmigaOS 2.x/3.x build. This feature works by replacing calls to the
CreateDir(), DeleteFile(), Lock(), MakeLink(), Open(), Rename(),
SetComment(), SetFileDate(), SetOwner() and SetProtection() functions
with a call to a front-end which breaks down long path names into
the individual path components. This is a compile-time option which
is enabled through the "library/stdio_long_path.h" header file.
Note that this feature is by default disabled for AmigaOS 4 because
its dos.library already transparently performs the long path
processing.
- The raise() function no longer directly calls abort() because that
function in turn would have invoked raise(SIGABRT), triggering an
infinite loop. Instead, raise() now invokes the __abort() function
which abort() would have called via raise(SIGABRT).
- fgets() no longer leverages the __getc() macro, which in the
original implementation added excessive overhead for even small
read operations. Instead, fgets() now focuses on copying data
stored in the FILE read buffer, transferring the buffered data
in bulk, if possible. The same kind of changes are present in
the gets() function.
- fputs() and puts() no longer leverage the __putc() macro. As with
the fgets() implementation, the focus is now on enabling bulk
data transfer, eliminating the __putc() macro overhead. For line
buffered output, both fputs() and puts() will check if the text
ends with a line feed and, if so, will output everything up to
and including the line feed. If enabled, Ctrl+C checking will
occur for every single line written.
- fread() and fwrite() no longer leverage the __getc() and
__putc() macros. Their focus is on enabling bulk data transfer
instead.
- The setvbuf() function now correctly sets the buffer size to the
value of BUFSIZ if a buffer size of 0 is specified. Previously,
setvbuf() would have disabled buffering for the FILE instead (this
was a bug).
Failure to allocate a buffer of the specified non-zero size is
now caught and results in the setvbuf() function to indicate
failure, setting the errno variable to ENOBUFS.
- The alloca() library function (which is a built-in function for
gcc, for example) now calls abort() rather than returning NULL.
- Changed the numeric overflow check which the calloc() function
uses, simplifying it.
- The memory management debugging code in stdlib_free.c is no longer
reusing the allocation size value to indicate that an allocation
should never be freed. This indication is now stored in a separate
flags field.
- The memory debugging code in malloc() now checks if the combined
size of the management data structures and front/back padding
stay within the bounds of a 32 bit integer.
The list of memory nodes to be freed is now initialized first.
Previously, the list would be left uninitialized if the attempt to
allocate memory for memory arbitration semaphore had failed.
- The realloc() function now obtains the original size of the
allocation from a dedicated field of the data structure which
precedes the allocation, whose purpose is to track the
allocation until it is freed. Previously, obtaining the relevant
allocation size information was encapsulated by a "clever"
macro.
With memory debugging enabled, the stored allocation size no
longer says how much memory, padding included, is being used.
Instead, the requested allocation size is stored unchanged, with
the total allocation size derived from this number. The idea is
to make it harder to mistake the original allocation size for
the padded one and vice versa.
- The use of the optional slab allocator now has to be deliberately
enabled in the "library/stdlib_memory.h" header file.
- The minimum size of an allocation managed by the optional slab
allocator is now 16 bytes instead of 8 because the management
data structure for each allocation now includes a flags field.
- The minimum size of a slab is now 4096 bytes.
- The optional slab allocator now checks for integer overflows when
processing allocation requests, taking into account the size of
the actual allocation, including padding. The task of figuring
out how much padding is needed now rests in a function which
calculates the total overhead.
- The usleep() function now correctly returns 0 and the function
prototype reflects this, too. Thanks go to capehill who raised
this issue.
- The "struct dirent" which is used by the readdir() function now
features a "d_type" member which indicates the kind of directory
entry the respective entry represents. For the time being,
the type can be one of DT_DIR (directory, or hard link to a
directory), DT_REG (file, or hard link to a file) or DT_LINK (soft
link). How do you know if the "d_type" member is available?
Check if the _DIRENT_HAVE_D_TYPE macro is defined. If it is, then
you can make use of the "d_type" member.
- Implemented the fixes for the tgamma() and tgammaf() functions
which were prompted by sodero. Thank you very much!
- The sqrt() function now returns a plain NAN if the function
parameter is < 0. Thanks go to sodero for providing the fix.
- The definition of "locale_t" is now based upon an incomplete
structure, with locale_t being a pointer to it. This change was
was provided by sacredbanana. Thank you very much!
amiga.lib 1.216 (10.7.2025)
- Added a 'C' implementation of the pools.lib functions which were
merged with the Kickstart/Workbench 3.0 era amiga.lib. This
implementation provides the LibDeletePool(), LibCreatePool(),
LibAllocPooled() and LibFreePooled() functions which had not
been available before in clib2.
Please note that these functions are largely obsolete and only
helpful for code which must run on Kickstart 2.04. The current
implementation performs no error checking for integer overflows,
just like the original pools.lib implementation.
c.lib 1.216 (xxx)
- Add some wchar and multibyte-string related functions to allow gcc
building a libstdc++ library with wide char support. For now, the
functions are mostly stub ones only. They can be implemented on
demand.
c.lib 1.215 (26.6.2017)
- Added -fno-aggressive-loop-optimizations option when building crtbegin.c
to work around constructor/destructor hack with GCC 5.4.0 on AmigaOS 4.
- Added -fno-builtin option to fix conflicts with builtin memset()
with GCC 5.4.0 on AmigaOS 4.
c.lib 1.214 (27.4.2017)
- Added integer overflow test to calloc().
- Tiny change in getopt_long() so that the value pointed to by longindex
is always initialized to an invalid index position (that being -1),
instead of 0. The value of 0 can break some shell commands, most notably
GNU wget.
c.lib 1.213 (4.12.2016)
- Added the __decay_unused_slabs() function which brings all currently
empty slabs which are still protected from reuse closer to getting
reused or released.
- The slab-test program now exercises the memory allocation functions
to a greater degree. Memory is allocated in random chunk sizes,
the allocations are resized (to other random chunk sizes),
33% of all allocations are randomly freed, empty slabs readied for
reuse then discarded. The output in JSON format now shows a bit
more information as to what is being done.
- Rewrote __get_slab_stats() to use setjmp() and longjmp() in the
print() callback invocation.
- __get_slab_stats() now reports how many times a slab was reused
after having stuck around in the "empty slab" list.
- Changing the slab size through an environment variable is now
a feature of the debug build.
- Small changes to allow the library to be built with SAS/C again.
This includes adding code to disable/re-enable profiling,
fixing "stdlib_profile.h" and updating the smakefiles.
- Still not sure what it does, but _CXV45 now sits along with _CX25
and _CX35 in "sas_cxv.asm". "sas_cxv54.asm" is not needed any
more.
- Found the last use of MEMF_PRIVATE which should have been compiled
only for the OS4 version.
c.lib 1.212 (27.11.2016)
- Unused slabs which get recycled are no longer reinitialized from
scratch if their chunk size matches what the allocator needed.
If the chunk size matches, the list of available chunks is
left unchanged, and just the various counters are reset.
- Added __get_slab_stats() function.
- Added support for global __slab_purge_threshold tuning variable.
c.lib 1.211 (23.11.2016)
- Added more consistency checking to the slab allocator, which is
built if DEBUG is defined in "stdlib_slab.c".
- Memory allocations are no longer guaranteed to be aligned to
64 bit word boundaries. In fact, this has not even worked
reliably in the past 10 years.
- Memory allocation request sizes are now rounded to multiples of
32 bit words (the size of an address pointer) instead to the
size of a 64 bit word.
- Reduced the memory footprint of the memory allocation management
data structures by reusing the most significant bit of the
memory allocation size. This allows many more allocations to fit
into the 32 byte chunk slabs, but limits the maximum memory
allocation size to a little less than 2 GBytes.
- Added integer overflow checks to the memory management code.
- Reduced the memory management overhead further. This cuts an
additional 8 bytes per allocation, unless neither the slab
allocator nor memory pools are available. With this reduction
the slab allocator is able to use 16 byte chunks, which cover
memory allocation requests of 1..8 bytes.
- Fixed a bug caused by returning an allocation back to a slab
which passed the wrong pointer.
c.lib 1.210 (22.11.2016)
- Added __get_slab_allocations() function which will report information
about each memory allocation made by the slab allocator which does
not come from a slab.
- If the first slab in the list of slabs which share the same chunk
size has no more room, it means that all other slabs following
it have no room either. This speeds up the test to find a slab with
free space, which can now abort and directly proceed to allocate
memory for a new slab.
- If an empty slab's decay count hits zero, it is moved to the front
of the empty slab list to be reclaimed more quickly.
- Allocations made from the slab now carry a pointer back to the
slab which they are a part of. This speeds up deallocation but
has the downside of making the smallest usable slab chunk size
64 bytes, which is double what used to be the minimum before.
c.lib 1.209 (21.11.2016)
- The maximum slab size is now 2^17 bytes (= 131072). If you request
a slab size larger than this, you will get slab sizes of 131072
bytes instead.
- Enabling the memory management debugging code no longer produces
compiler errors.
c.lib 1.208 (19.11.2016)
- Updated <stdlib.h> with new functions and data structures for
use with the slab allocator.
- Added __get_slab_usage() function which can be used to query
the slab allocator memory usage at runtime.
c.lib 1.207 (18.11.2016)
- Added a slab allocator which replaces the use of memory pools or the
plain AllocMem() operations, respectively. In order to activate the
slab allocator, choose a slab size (e.g. 2048 bytes or 4096 bytes)
and declare a global variable like this:
ULONG __slab_max_size = 2048;
Memory allocations smaller than the slab size will be made from
"slabs", i.e. large chunks of memory of the given size. Larger
allocations will be managed separately.
m.lib 1.206 (24.4.2015)
- The fscanf() family failed to parse and convert %f parameters correctly
if the respective number did not begin with a digit, but a decimal
point. Hence ".7" would not be processed, but "0.7" would.
c.lib 1.206 (24.4.2015)
- Reworked the __putc() and putc() macros to reference the 'c' input
parameter only once, and to be free of side-effects when tinkering
with the buffer position.
- isatty() had the __fd_lock() call in the wrong place, which could have
led to cleanup problems later.
- The close action in the stdio, socket and termios hook code now
also zaps the fd pointer itself after cleaning up the file descriptor
table entry.
- Removed the remains of all the stack extension and stack overflow/underflow
checking code. It never actually worked. The bit that does work is the stack
usage measurement code, plus the bit that sets up the custom stack
according to local setting or by calling a query function.
c.lib 1.205 (21.8.2010)
- Added dlclose(), dlerror(), dlopen() and dlsym() functions, which are
@@ -1172,7 +1488,7 @@ c.lib 1.187 (29.1.2005)
adding/subtracting the local time zone.
- Changed the algorithm that calculates the number of days that have passed
so far as used by the the __convert_time() function and the conversion
so far as used by the __convert_time() function and the conversion
code in strftime().
- Also changed the algorithm used by strftime() to produce the week numbers
