POSIX

defines bindings for most posix APIs.

If a header is added, all of it must be implemented.

Each platform must define the exact same symbols, different values are allowed, even structs with different non-standard fields.

APIs part of extensions may be left out completely if one target doesn't implement it.

APIs with a direct replacement in core might not be implemented.

Macros are emulated with force inlined functions.

Struct fields defined by the posix standard (and thus portable) are documented with [PSX].

ADD A TEST FOR SIGINFO, one thread signalling and retrieving the signal out of siginfo or something. ADD A TEST FOR wait.h ADD A TEST FOR pthread. ADDD A test for stat.h. ADD A TEST FOR setjmp.h. HAIKU.

Unimplemented POSIX headers:

• aio.h
• complex.h | See core:c/libc and our own complex types
• cpio.h
• ctype.h | See core:c/libc for most of it
• ndbm.h | Never seen or heard of it
• fenv.h
• float.h
• fmtmsg.h
• ftw.h
• semaphore.h | See core:sync
• inttypes.h | See core:c
• iso646.h | Impossible
• math.h | See core:c/libc
• mqueue.h | Targets don't seem to have implemented it
• regex.h | See core:regex
• search.h | Not useful in Odin
• spawn.h | Use fork, execve, etc.
• stdarg.h | See core:c/libc
• stdint.h | See core:c
• stropts.h
• syslog.h
• pthread.h | Only the actual threads API is bound, see core:sync for synchronization primitives
• string.h | Most of this is not useful in Odin, only a select few symbols are bound
• tar.h
• tgmath.h
• trace.h
• wchar.h
• wctype.h

• time.h | Docs
