From 3fffa6c6072826f70aebe72863968bffb9d714cc Mon Sep 17 00:00:00 2001 From: Ingo Schwarze Date: Fri, 6 Nov 2015 16:30:33 +0000 Subject: Use getprogname(3) rather than __progname. Suggested by Joerg@ Sonnenberger (NetBSD). Last year, deraadt@ confirmed on tech@ that this "has the potential to be more portable", and micro-optimizing for speed is not relevant here. Also gets rid of one global variable. --- compat_progname.c | 42 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 42 insertions(+) create mode 100644 compat_progname.c (limited to 'compat_progname.c') diff --git a/compat_progname.c b/compat_progname.c new file mode 100644 index 00000000..9840cc7c --- /dev/null +++ b/compat_progname.c @@ -0,0 +1,42 @@ +#include "config.h" + +#if HAVE_PROGNAME + +int dummy; + +#else + +/* $Id: compat_progname.c,v 1.1 2015/11/06 16:30:33 schwarze Exp $ */ +/* + * Copyright (c) 2015 Ingo Schwarze + * + * Permission to use, copy, modify, and distribute this software for any + * purpose with or without fee is hereby granted, provided that the above + * copyright notice and this permission notice appear in all copies. + * + * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES + * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF + * MERCHANTABILITY AND FITNESS.
