<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>

<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><math-68881.h></tt> file written by Matthew Self <tt>(self [at] bayes.arc.nasa.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><workbench/startup.h></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><stddef.h></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><dos/dos.h></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><dos/dos.h></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 > 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><unistd.h></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><dos.h></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>

This is a collection of programs I'm using to test the library. These
|

are functional tests: the library is supposed to do something, and produce
|

a particular result. For example, "printf_test" exercises a bunch of
|

output formatting rules.

What's this stuff for ? I use it in SP_Engine to hide the usual bunch of "secret
|
||||
messages". As you can see, the strings are simply not'ed .
|
||||
This source shows both flaws: fgets() and the missing buffer flush. You can
|
||||
change the while() statement with
|
||||
|
||||
while(!feof(filein))
|
||||
{
|
||||
fgets(in_linebuffer, LINEBUFLENGTH, filein);
|
||||
....
|
||||
|
||||
This way you'll workaround the first problem.
|
||||
The second issue manifests itself this way: the last two fputs() followed by the
|
||||
fclose() don't do anything: no "};\n" and no "unsigned....." lines are output to
|
||||
'fileout'. With SAS, it works perfectly. Converting the source to dos.library
|
||||
calls also works perfectly. I wonder if there's some kind of strange interaction
|
||||
with the dos/shell updates.
