On failure an explanation will be printed to stderr, obtained from explain_wait(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_wait_or_die(status); status The status, exactly as to be passed to the wait(2) system call.
