On failure an explanation will be printed to stderr, obtained from explain_wait4(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_wait4_or_die(pid, status, options, rusage); pid The pid, exactly as to be passed to the wait4(2) system call. status The status, exactly as to be passed to the wait4(2) system call. options The options, exactly as to be passed to the wait4(2) system call. rusage The rusage, exactly as to be passed to the wait4(2) system call. Returns: This function only returns on success, see wait4(2) for more information. On failure, prints an explanation and exits.
