This is fine, although I would rather prefix the macro name with TST_ or LTP_ and once the pthread_once_t variable is hidden from the global namespace we don't have to prefix it with name_fn. If you are OK with these changes, I can commit modified version right away ;). -- Cyril Hrubis [email protected] ------------------------------------------------------------------------------ Flow-based real-time traffic analytics software.
