lib/libc_r/uthread pthread_private.h
Log:
Provide more POSIX-complaint ttyname_r(3) interface[1], which is slightly
different from what has been offered in libc_r (the one spotted in the
original PR which is found in libthr has already been removed by David's
commit, which is rev. 1.44 of lib/libthr/thread/thr_private.h):
- Use POSIX standard prototype for ttyname_r, which is,
int ttyname_r(int, char *, size_t);
Instead of:
char *ttyname_r(int, char *, size_t);
This is to conform IEEE Std 1003.1, 2004 Edition [1].
- Since we need to use standard errno for return code, include
errno.h in ttyname.c
- Update ttyname(3) implementation according to reflect the API
change.
- Document new ttyname_r(3) behavior
- Since we already make use of a thread local storage for
ttyname(3), remove the BUGS section.
- Remove conflicting ttyname_r related declarations found in libc_r.
Hopefully this change should not have changed the API/ABI, as the ttyname_r
symbol was never introduced before the last unistd.h change which happens a
couple of days before.
