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. SEE ALSO
