From 3cf31a194f5721b67b1255e3f168d4bc87d433fc Mon Sep 17 00:00:00 2001
From: Jeremy Allison <jra@samba.org>
Date: Tue, 15 Feb 2000 19:36:47 +0000
Subject: Added replacement functions sys_popen and sys_pclose. These are based
 on the glibc source code and are safer than the traditional popen as they
 don't use a shell to exec the requested command. Now we have these functions
 they can be tightened up (environment etc.) as required to make a safe popen.
 It should now be safe to add the environement variable loading code to
 loadparm.c Jeremy. (This used to be commit
 b52e92b09d4ca3b66e534f520468dee27065d048)
