files which initialize global data, such as the new "stdlib_program_name.c"
and "stdlib_malloc.c".
- Until I can find a way to invoke it from within the library, the
__machine_test() function is no longer invoked.
- Tagged global data with NOCOMMON attributes.
- Added the __lib_init() and __lib_exit() functions, which are part of the
thread-safe library and which can be used to hook up clib2 with standard
Amiga shared library/device code. Some documentation on how to use them
can be found in the <dos.h> header file.

a separate file.
- Simplified the library/open close code in "stdlib_main.c".

- Dropped unused stub code which is now redundant because of
the constructor/destructor mechanism.

that the constructors/destructors are called in the proper
order, too.

or initializes it.
- The stdlib constructor now performs the CPU/FPU compatibility test.

initialization code for the stdin/stdout/stderr streams and
out of the program parameter setup.
- The current program name is now set up in the stdlib
initialization function.
- Simplified the machine test code; moved the FPU check into
the math initialization code.
- Added more safety checks to verify that file descriptor
file handles are valid.

routine. We no longer allocate memory and then modify it, but
call a function for each quoted parameter which does whatever is
necessary.
- The shell command parameter parser now considers the non-breaking
space character (ISO code 160) to be a blank space character, too.

Both the library and the user code need to be rebuilt with the
preprocessor symbol __THREAD_SAFE defined to get thread-safe
code.
git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@14843 87f5fb63-7c3d-0410-a384-fd976d0f7a62
and dirent data operations. That should do it! While the library is
not reentrant (this is not ixemul.library) it should be thread-safe
now. Thread-safe in the sense of POSIX 1003.1c-1995.
git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@14842 87f5fb63-7c3d-0410-a384-fd976d0f7a62
and ftrylockfile().
- Modified the internal FILE structure to allow for thread locking.
Note that this again requires that the library is rebuilt!
- Added or modified macros for getc_unlocked(), getchar_unlocked(),
putc_unlocked() and putchar_unlocked().
- Added rand_r().
- Added flockfile()/funlockfile() wrappers around all stdio
functions.

parameters (which is by default linked in with libunix.a),
regular expressions can no longer prompt dos.library requesters
to appear. However, to be on the safe side, if you are expecting
to pass regular expressions on the command line, do not use
the wildcard expansion code such as by overriding the library
symbols with dummy functions such as are used in the file
"stdlib_wildcard_expand.c".
- Added a new variable '__open_locale' which can be used to
restrict all library functions to use the "C" language locale
rather than the current system locale settings. In addition
to that, two new functions __locale_exit() and __locale_init()
can be used to close and (re-)open the system locale at a
later time.
- Local ("static") functions are now identified by the STATIC
qualifier. This was done in preparation for changes that will
deal with global and local data and the issue of thread safety.

code. Also, the contents of the AnchorPath structure are no longer
modified between calls. MatchEnd() has to be sufficient.

management code in the default link library along with the
normal versions. Let's see how well this works out in the GCC
version. SAS/C does not seem to like it...
git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@14785 87f5fb63-7c3d-0410-a384-fd976d0f7a62
malloc/free code itself and updated the alloca code to do its
own data management.
- Finally optimized the alloca() memory cleanup code.

- Fixed a typo in the hstrerror() function.
git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@14782 87f5fb63-7c3d-0410-a384-fd976d0f7a62
be part of amiga.lib. While comparable functionality is available
in rexxsyslib.library V45, the new stubs might be helpful during
porting. Care must be taken since these functions don't work
exactly like the originals.
- Integrated strlcpy() and strlcat() which are intended to be safer
replacements for strncpy() and strncat().
- The program's task priority is now configurable through an external
variable '__priority'.
- The process name to be used when detaching can be configured through
the new '__process_name' variable.
- The minimum required operating system version can be configured
through the new '__minimum_os_lib_version' variable; a matching
error message can be provided through the new '__minimum_os_lib_error'
variable.
- The default console window specification can be overriden through
the new '__stdio_window_specification' variable.
- The socket initialization code did not set up a reference to the
'h_errno' variable correctly. This had the effect of making name
and address resolution errors trash the 'errno' variable instead
and leaving 'h_errno' always set to 0. Fixed.
