NAME
       program_invocation_name,  program_invocation_short_name	-  obtain name
       used to invoke calling program

SYNOPSIS
       #define _GNU_SOURCE
       #include 

       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.
