Function Documentation

gc_dequeue_status_t gc_jd_queue_dequeue	(	gc_eaddr_t	q,
		gc_eaddr_t *	item_ea,
		int	jd_tag,
		gc_job_desc_t *	item
	)

Remove and return item at head of queue.

Parameters:

[in]	q	is EA address of queue structure.
[out]	item_ea	is EA address of item at head of queue.
[in]	jd_tag	is the tag to use to get the LS copy of the item.
[out]	item	is local store copy of item at head of queue.

Returns:

false if the queue is empty, otherwise returns true and sets item_ea and DMA's job descriptor into item

If return is not GCQ_OK, we're holding a lock-line reservation that covers the queue.
