explain_waitpid_or_die(3)  Library Functions Manual  explain_waitpid_or_die(3)

NAME
       explain_waitpid_or_die  -  wait	for process to change state and	report
       errors

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) sys-
       tem  call.   On	failure	 an explanation	will be	printed	to stderr, ob-
       tained from explain_waitpid(3), and  then  the  process	terminates  by
       calling exit(EXIT_FAILURE).

       This  function  is intended to be used in a fashion similar to the fol-
       lowing example:
	      explain_waitpid_or_die(pid, status, options);

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

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

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

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