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_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.
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.
