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. --- include/errno.h | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'include') diff --git a/include/errno.h b/include/errno.h index 9e1e3202..0361b33a 100644 --- a/include/errno.h +++ b/include/errno.h @@ -5,6 +5,8 @@ extern "C" { #endif +#include + #include #ifdef __GNUC__ @@ -13,6 +15,10 @@ __attribute__((const)) int *__errno_location(void); #define errno (*__errno_location()) +#ifdef _GNU_SOURCE +extern char *program_invocation_short_name, *program_invocation_name; +#endif + #ifdef __cplusplus } #endif -- cgit v1.2.1
