NAME
program_invocation_name, program_invocation_short_name - obtain name used to invoke calling program
SYNOPSIS
#define _GNU_SOURCE
#include <errno.h>
extern char *program_invocation_name;
extern char *program_invocation_short_name;
DESCRIPTION
program_invocation_name
contains 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_name
is global.
program_invocation_short_name
contains 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]/cmdline
file provides access to similar information.
