NAME

program_invocation_name, program_invocation_short_name - obtain name used to invoke calling program  

SYNOPSIS

#define _GNU_SOURCE         /* See feature_test_macros(7) */
#include <errno.h>extern char *program_invocation_name;extern char *program_invocation_short_name;
 

DESCRIPTION

program_invocation_namecontains the name that was used to invoke the calling program. This is the same as the value of argv[0]in main(), with the difference that the scope of program_invocation_nameis global.

program_invocation_short_namecontains the basename component of name that was used to invoke the calling program. That is, it is the same value as program_invocation_name, with all text up to and including the final slash (/), if any, removed.

These variables are automatically initialized by the glibc run-time startup code.  

CONFORMING TO

These variables are GNU extensions, and should not be used in programs intended to be portable.  

NOTES

The Linux-specific /proc/[number]/cmdlinefile provides access to similar information.
