Both the 68k and PowerPC platform now invoke them in the same order
and the 68k code uses the designated invocation priorities. The
PowerPC destructor function now sets up the exit() jmp_buf before
the destructor functions are called.

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.

harder to break code by accidentally forgetting to call
InitSemaphore() after having allocated the memory for it.

not reentrant (this is not ixemul.library) it should be thread-safe
now. Thread-safe in the sense of POSIX 1003.1c-1995.

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.

function pointers alone. The utility.library/CallHookPkt mechanism
is no longer required.
- Moved the entire lseek() code relevant for files into the hook
function.
- Simplified the close() function which now just calls into the
hook code to perform whatever is necessary. The hook code is
responsible for cleaning up after aliases, etc. This change in
turn made it possible to greatly simplify the hook code for
buffered files which now bypasses close/read/write/lseek and
directly invokes the hook code for unbuffered files.

the file descriptor hook and into the respective functions,
such as dup2(), fchmod(), fchown(), fcntl(), fdatasync(), fstatfs(),
fsync(), ftruncate() and lseek(). Code which is not strictly
required will no longer find its way into your programs if you
link with the updated library.
NOTE: these changes require that the entire library is rebuilt!

code which initialized them.
- Reading/changing the errno variable is no longer done directly, but
involves accessor functions.
- References to the HUGE_VAL quantity now involve an accessor function, too.
- Changed the manner in which the __huge_val constant is initialized by
the __math_init() function.

so far as used by the the __convert_time() function and the conversion
code in strftime().
- Also changed the algorithm used by strftime() to produce the week numbers
(the '%U' and '%W' format specifiers). The new method is much simpler
than the old one.
- Made the code that converts a 'time_t' value into the 'struct DateStamp',
as used by strftime() and utime(), into its own function. This also
fixes a bug in the code strftime() would use which was completely
unaware of the local time zone settings.

- The fall-back function for converting time into a string in strftime()
now calls itself for the "%x" and "%X" format specifiers.

to the built-in function.
- Updated the stdio.h, stdlib.h, string.h and unistd.h header files
to declare function prototypes for the __MEM_DEBUG versions of the
library functions only if that preprocessor symbol is defined.
- If a SIGINT signal is caught and processed by the default signal
handler, the localized "*** BREAK" string will be printed rather
than the built-in one.

normal versions. Let's see how well this works out in the GCC
version. SAS/C does not seem to like it...

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.

- Cleaned up the OS4 build makefile, losing redundant libraries,
adding more startup object code and ultimatively making the whole
rebuild logic work again: if code changes and dependencies are
set up correctly, it will now get rebuilt. Previously, such
changes went unnoticed and you had to rebuild the entire library
from scratch.
- Added stubs for CreatePort(), DeletePort(), CreateTask(), DeleteTask()
and NewList() which have equivalents in exec.library V50 but for which
it might be useful if ported code didn't have to reference these
explicitly.
- mktemp() was broken in libunix.a with Unix path semantics enabled.
This was because the name template was translated and translated
back again, overwriting the translation buffer. This, funny enough,
broke Samba's printing feature. Fixed by translating the name only
before each test for "uniqueness" is made. The new code also handles
empty "" templates gracefully, which was a problem with both the
"standard" and the Unix path semantics flavour.
Why is it that I find bugs like this always after having just
released another library update?

- The scanf() family now always returns the number of assignments made
unless an error occured or an EOF was hit during conversion before the
first assignment could be made.
- strtok() did not terminate properly if the last token in the string
did not end with a separator character but with a '\0' byte. Fixed.
- The directory scanning functions opendir/closedir did not get the global
directory data tracking data structure initialized which later led to
Enforcer hits and maybe trashed memory. Fixed.

- Moved the locale initialization/cleanup code into constructors
and destructors.
- The socket cleanup function is now a destructor.
- The math cleanup function is now a destructor.
- The wildcard cleanup function is now a destructor.
- The stdio cleanup function is now a destructor.
- The stack extension cleanup function is now a destructor.
- The code that cleans up after the program's current directory
was changed is now a destructor function.
- Moved the initialization/cleanup code for unlink() into constructors
and destructors.
- Moved the initialization/cleanup code for usergroup.library into
constructors and destructors.
- Added usleep(), and created wrapper code that both sleep() and
usleep() can use.
- Added strtoll() and strtoull(), with further changes to <limits.h>
and <stdlib.h>.

- The <assert.h> header file was missing the C++ 'extern "C" { .. }'
declarations.
- Added a new function __get_default_file() which allows direct access
to the low level file handle/socket descriptor associated with a
file descriptor.

- Added "math_hypot.c"

- Added h_strerror() function to libnet.a; there's a global 'h_errno'
variable available, too.
- <signal.h> now defines a type 'sig_t'.
- <unistd.h> now allows the 'fd_set' type to be referenced as
'struct fd_set', too.
