Function Documentation

ownDataRefQueueEnqueueReadyRef()

vx_status ownDataRefQueueEnqueueReadyRef	(	tivx_data_ref_queue	data_ref_q,
		vx_reference	ref
	)

Enqueue 'ref' into 'READY' queue.

if queue is full, VX_FAILURE is returned.

NOTE, this is a non-blocking API.

ownDataRefQueueDequeueDoneRef()

vx_status ownDataRefQueueDequeueDoneRef	(	tivx_data_ref_queue	data_ref_q,
		vx_reference *	ref
	)

Dequeue 'ref' from 'DONE' queue.

if queue is empty VX_FAILURE is returned and 'ref' is set to NULL

NOTE, this is a non-blocking API.

ownDataRefQueueWaitDoneRef()

vx_status ownDataRefQueueWaitDoneRef	(	tivx_data_ref_queue	data_ref_q,
		vx_uint32	timeout
	)

Wait for 'DONE' queue to be non-empty.

if 'timeout' units of time elapses then VX_FAILURE is returned

NOTE, this is a blocking API and block for 'timeout' units of time
