Detailed Description

Interface to Event Queue APIs.

Event Queue can be used to collect framework generated events into a queue. When user calls vxWaitEvent the event is returned to the user in a first-in first out manner

Enumeration Type Documentation

◆ tivx_queue_type_e

enum tivx_queue_type_e

Type of event that can be generated during system execution.

Enumerator

TIVX_EVENT_GRAPH_QUEUE

Graph event queue.

The registered event will be used in the graph event queue

TIVX_EVENT_CONTEXT_QUEUE

Context event queue.

The registered event will be used in the context event queue

Definition at line 131 of file tivx_event_queue.h.

Function Documentation

◆ ownEventQueueCreate()

vx_status ownEventQueueCreate ( tivx_event_queue_t * event_q )

Create a event queue.

Returns: event queue handle on success, else error

◆ ownEventQueueDelete()

void ownEventQueueDelete ( tivx_event_queue_t * event_q )

Delete a event queue.

Returns: event queue handle on success, else error

◆ ownEventQueueAddEvent()

vx_status ownEventQueueAddEvent	(	tivx_event_queue_t *	event_q,
		vx_enum	event_id,
		uint64_t	timestamp,
		uint32_t	app_value,
		uintptr_t	param1,
		uintptr_t	param2,
		uintptr_t	param3
	)

Add event to event queue.

When events are disabled, event is not added to the event_q
