delphij 2005-05-13 16:27:31 UTC FreeBSD src repository Modified files: include unistd.h lib/libc/gen ttyname.3 ttyname.c 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.
