Member Function Documentation

SINT32 CAThreadPool::addRequest	(	THREAD_MAIN_TYP	routine,
		void *	args
	)

Adds a new request (task) to this threadpool.

Return values:

E_SPACe	if there was no more space in the waiting queue and we do not want to wait for an other request to finish
E_SUCCESS	if this request was added to the working queue
