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

NAME
       programinvocationname,  programinvocationshortname  -  obtain name
       used to invoke calling program

SYNOPSIS
       #define GNUSOURCE         /* See featuretestmacros(7) */
       #include 

       extern char *programinvocationname;
       extern char *programinvocationshortname;

DESCRIPTION
       programinvocationname 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  programinvocationname  is
       global.

       programinvocationshortname  contains  the basename component of name
       that was used to invoke the calling program.  That is, it is  the  same
       value as programinvocationname, 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.
