SYNOPSIS
     #include <libexplain/waitpid.h>
     int pid = explain_waitpid_or_die(int pid, int *status, int options);

DESCRIPTION
     The  explain_waitpid_or_die  function is used to call the waitpid(2) system
     call.  On failure an explanation will be printed to stderr,  obtained  from
     explain_waitpid(3),   and	 then	the   process	terminates   by  calling
     exit(EXIT_FAILURE).

     example:
	    explain_waitpid_or_die(pid, status, options);

     status  The status, exactly as to be passed to the waitpid(2) system call.

     options

     Returns:
	     This  function  only returns on success.  On failure, prints an ex-
	     planation and exits.
