From 336dfb2d27fdd4c8fb69b5aee7817b595bb23691 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sun, 14 Mar 1999 21:12:49 +0000 Subject: Update. 1999-03-13 Mark Kettenis * 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 * 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 * manual/llio.texi (File Position Primitive): Reformat @end command. Patch by Bruno Haible [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. --- sysdeps/generic/utmp_file.c | 13 ++++++++++++- 1 file changed, 12 insertions(+), 1 deletion(-) (limited to 'sysdeps/generic') diff --git a/sysdeps/generic/utmp_file.c b/sysdeps/generic/utmp_file.c index ddf49467ef..74e91fb948 100644 --- a/sysdeps/generic/utmp_file.c +++ b/sysdeps/generic/utmp_file.c @@ -1,4 +1,4 @@ -/* Copyright (C) 1996, 1997, 1998 Free Software Foundation, Inc. +/* Copyright (C) 1996, 1997, 1998, 1999 Free Software Foundation, Inc.
