From a3e03be058a9b9a2caf36c5b18f66c0fc3df3bf0 Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Tue, 8 May 2001 19:58:20 +0000 Subject: Add in libutil, based on Cory Visi's variant of Michael Shmulevich's libutil port. I have reworked the code quite a bit so that the stuff that is supposed to be in libc is in libc, and I added a bunch of missing stuff so the libutil interface matches that of glibc's libutil. The only caveat is that libutil/login.c is currently a stub. -Erik --- libutil/forkpty.c | 52 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 52 insertions(+) create mode 100644 libutil/forkpty.c (limited to 'libutil/forkpty.c') diff --git a/libutil/forkpty.c b/libutil/forkpty.c new file mode 100644 index 000000000..af1d4becc --- /dev/null +++ b/libutil/forkpty.c @@ -0,0 +1,52 @@ +/* Copyright (C) 1998 Free Software Foundation, Inc. + This file is part of the GNU C Library. + Contributed by Zack Weinberg , 1998. + + 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.
