On failure an explanation will be printed to stderr, obtained from the ex- plain_execv(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_execv_on_error function is used to call the execv(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_execv(3) function, but still returns to the caller. pathname The pathname, exactly as to be passed to the execv(3) system call. argv The argv, exactly as to be passed to the execv(3) system call. RETURN VALUE The explain_execv_or_die function only returns on success, see execv(3) for more information. On failure, prints an explanation and exits, it does not return. The explain_execv_on_error function always returns the value return by the wrapped execv(3) system call.
