INVOCATION_NAME(3)         Linux Programmer's Manual        INVOCATION_NAME(3)

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.
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 simi-
       lar information.
