From b4ea63856a6af3d1bcc2db12537785371ac2024c Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Sat, 6 Apr 2013 17:50:37 -0400 Subject: add support for program_invocation[_short]_name this is a bit ugly, and the motivation for supporting it is questionable. however the main factors were: 1. it will be useful to have this for certain internal purposes anyway -- things like syslog. 2. applications can just save argv[0] in main, but it's hard to fix non-portable library code that's depending on being able to get the invocation name without the main application's help. --- src/internal/libc.c | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'src/internal/libc.c') diff --git a/src/internal/libc.c b/src/internal/libc.c index d22d2747..942f6b44 100644 --- a/src/internal/libc.c +++ b/src/internal/libc.c @@ -16,3 +16,7 @@ __asm__(".hidden __libc"); size_t __hwcap; size_t __sysinfo; +char *__progname=0, *__progname_full=0; + +weak_alias(__progname, program_invocation_short_name); +weak_alias(__progname_full, program_invocation_name); -- cgit v1.2.1
