From e4cf5070694529a8779d5e1581567bcfb9307da0 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Mon, 2 Dec 1996 04:00:15 +0000 Subject: update from main archive 961201 Mon Dec 2 03:59:38 1996 Ulrich Drepper * grp/initgroups.c: Update and reformat copyright. Use __getgrent_r instead of getgrent. * inet/rcmd.c: Update and reformat copyright. Use __gethostbyname_r instead of gethostbyname. * inet/rexec.c: Likewise. * intl/finddomain.c: Correct comment about CEN sponsor and revision. * locale/findlocale.c: Likewise. * intl/l10nflist.c: Correct handling of CEN sponsor and revision. * locale/Makefile (CPPFLAGS): Add definition of LOCALEDIR. * locale/setlocale.c (setlocale): Correctly split value of LOCALE_PATH. * locale/programs/localedef.c: Use LOCALEDIR not LOCALE_PATH to find output directory. * nss/getXXbyYY.c [NEED_H_ERRNO]: Before enlarging buffer test h_errno_tmp variable. Save error value from being changed during `free' call. * nss/getXXent.c: Likewise. * nss/nss_files/files-XXX.c: Set h_errno variable to NETDB_INTERNAL before returning ERANGE error. * posix/glob.c: Use getlogin_r and getpwnam_r function when available or in GNU libc. * pwd/getpw.c: Use getpwuid_r instead of getpwuid. * sunrpc/clnt_gen.c: Use gethostbyname_r and getprotobyname_r. * sunrpc/clnt_simp.c: Likewise. * sunrpc/getrpcport.c: Likewise. * sysdeps/unix/sysv/linux/gethostid.c: Likewise. * posix/getconf.c: Treat _SC_UNIT_MAX and _SC_ULONG_MAX separately since the value might be outsode the range of the `long int'. Print string `undefined' when a value is undefined. * stdlib/l64a.c: Return correct pointer. Patch by NIIBE Yutaka . * string/Makefile (routines): Add argz-addsep. * string/argz-addsep.c: New file. * string/argz.h: Add prototypes for argz_add_sep. * string/argz-ctsep.c: Prevent memory leak. * string/strcoll.c: Correct typo in comment. Sat Nov 30 02:53:59 1996 Ulrich Drepper * sysdeps/unix/sysv/linux/sys/serial.h: Removed again. The file is not general enough to be part of the libc. * sysdeps/unix/sysv/linux/Dist: Remove sys/serial.h. * sysdeps/unix/sysv/linux/Makefile: Don't install sys/serial.h. Thu Nov 28 20:04:41 1996 Andreas Schwab * login/Makefile: Fix typo. * nss/Makefile (generated): Filter out db-alias.c. Thu Nov 28 14:44:01 1996 Andreas Schwab * time/Makefile (echo-zonenames): Don't depend on non-existing target `zonenames'. Thu Nov 28 12:34:05 1996 Andreas Schwab * link.h: New file. * nss/nsswitch.c: Use it. * printf.h: Fix file name. * stdlib/strfmon.c: Use it. --- pwd/getpw.c | 40 +++++++++++++++++++++++----------------- 1 file changed, 23 insertions(+), 17 deletions(-) (limited to 'pwd/getpw.c') diff --git a/pwd/getpw.c b/pwd/getpw.c index 402fafd7f0..9c2e4afd0a 100644 --- a/pwd/getpw.c +++ b/pwd/getpw.c @@ -1,23 +1,25 @@ /* Copyright (C) 1991, 1992, 1996 Free Software Foundation, Inc. -This file is part of the GNU C Library. + This file is part of the GNU C Library. -The GNU C Library is free software; you can redistribute it and/or -modify it under the terms of the GNU Library General Public License as -published by the Free Software Foundation; either version 2 of the -License, or (at your option) any later version. + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Library General Public License as + published by the Free Software Foundation; either version 2 of the + License, or (at your option) any later version. -The GNU C Library is distributed in the hope that it will be useful, -but WITHOUT ANY WARRANTY; without even the implied warranty of -MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
