Update.
1999-03-13 Mark Kettenis <kettenis@gnu.org>
* sysdeps/unix/bsd/getpt.c (__getpt): Do not use `isatty' to check
if the opened master pty really is a pty. `isatty' checks for
tty-ness and a pty is not a tty. Return ENOENT instead of ENFILE
if we are out of pty's.
1999-03-13 Mark Kettenis <kettenis@gnu.org>
* sysdeps/generic/utmp_file.c (setutent_file): Make sure the just
opened file is closed on exec.
* login/utmp_daemon.c (setutent_daemon): Likewise for the just
opened socket.
1999-03-13 Andreas Jaeger <aj@arthur.rhein-neckar.de>
* manual/llio.texi (File Position Primitive): Reformat @end
command. Patch by Bruno Haible <haible@ilog.fr> [PR libc/1020].
* nscd/nscd_getpw_r.c (nscd_getpw_r): Set `errno' correctly if no
entry is found.
* nscd/nscd_getgr_r.c (nscd_getgr_r): Likewise.
* nscd/nscd_gethst_r.c (nscd_gethst_r): Likewise.
