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) 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).

       This function is intended to be used in a fashion similar to the following 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.
