On failure an explanation will be printed to stderr, obtained from the ex- plain_pipe2(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

On failure an explanation will be printed to stderr, obtained from the explain_pipe2(3) function, but still returns to the caller. fildes The fildes, exactly as to be passed to the pipe2(2) system call. flags The flags, exactly as to be passed to the pipe2(2) system call. RETURN VALUE The explain_pipe2_or_die function only returns on success, see pipe2(2) for more information. On failure, prints an explanation and exits, it does not return. The explain_pipe2_on_error function always returns the value return by the wrapped pipe2(2) system call.
