Deprecated:: Deprecated since tizen 6.0. This group of functions is applied to an Ecore_Buffer_Consumer object. Ecore_Buffer_Consumer receives Ecore_Buffer enqueued by Ecore_Buffer_Provider. Consumer must release Ecore_Buffer when it's no longer used. Thus, the Ecore_Buffer_Provider is now free to re-use or destroy Ecore_Buffer.

Ecore_Buffer_Consumer

Deprecated:

Deprecated since tizen 6.0.

An object representing a consumer of Ecore_Buffer.

Since (EFL) :: 1.15

Ecore_Buffer_Consumer_Enqueue_Cb

Called whenever a Ecore_Buffer enqueued in buffer queue.

Deprecated:: Deprecated since tizen 6.0.

Since (EFL) :: 1.15

See also:: ecore_buffer_consumer_buffer_enqueued_cb_set()

Ecore_Buffer_Consumer_Provider_Add_Cb

Called whenever a Ecore_Buffer_Provider connected.

Deprecated:: Deprecated since tizen 6.0.

Since (EFL) :: 1.15

See also:: ecore_buffer_consumer_provider_add_cb_set()

Ecore_Buffer_Consumer_Provider_Del_Cb

Called whenever a Ecore_Buffer_Provider disconnected.

Deprecated:: Deprecated since tizen 6.0.

Function Documentation

Ecore_Buffer* ecore_buffer_consumer_buffer_dequeue ( Ecore_Buffer_Consumer * consumer )

Returns the latest Ecore_Buffer submitted by provider.

Deprecated:: Deprecated since tizen 6.0.

Since (EFL) :: 1.15

Parameters:

[in] consumer The Ecore_Buffer_Consumer to request for buffer

Returns:: Ecore_Buffer handle or NULL if acquirement failed.

See also:: ecore_buffer_consumer_buffer_release()

Consumer can store Ecore_Buffer submitted by Provider as much as size of queue which is passed as a argument of ecore_buffer_consumer_new().

Since :: 2.4

void ecore_buffer_consumer_buffer_enqueued_cb_set	(	Ecore_Buffer_Consumer *	consumer,
		Ecore_Buffer_Consumer_Enqueue_Cb	func,
		void *	data
	)

Sets a callback for enqueued buffer events.

Deprecated:: Deprecated since tizen 6.0.

Since (EFL) :: 1.15

Parameters:

[in]	consumer	The Ecore_Buffer_Consumer to set callbacks on
[in]	func	The function to call
[in]	data	A pointer to the user data to store.

A call to this function will set a callback on an Ecore_Buffer_Consumer, causing func to be called whenever consumer has received buffer submitted from provider.

You may success acquire Ecore_Buffer after this callback called.

Since :: 2.4

Eina_Bool ecore_buffer_consumer_buffer_release	(	Ecore_Buffer_Consumer *	consumer,
		Ecore_Buffer *	buffer
	)

Releases the acquired Ecore_Buffer.

Deprecated:: Deprecated since tizen 6.0.

Since (EFL) :: 1.15

Parameters:

[in]	consumer	The Ecore_Buffer_Consumer to request release buffer
[in]	buffer	The Ecore_Buffer to release

Returns:: EINA_TRUE on success, EINA_FALSE otherwise.

See also:: ecore_buffer_consumer_buffer_dequeue()

Consumer should release the Ecore_Buffer after acquiring and using it. By doing release, Ecore_Buffer will be used by provider again, or freed internally if Ecore_Buffer is not necessary anymore. If not, the resource of Ecore_Buffer is continually owned by consumer until released.

Since :: 2.4

void ecore_buffer_consumer_free ( Ecore_Buffer_Consumer * consumer )

Frees an Ecore_Buffer_Consumer.

Deprecated:: Deprecated since tizen 6.0.

Since (EFL) :: 1.15

Parameters:

[in] consumer The Ecore_Buffer_Consumer to free

This frees up any memory used by the Ecore_Buffer_Consumer.

Since :: 2.4

Ecore_Buffer_Consumer* ecore_buffer_consumer_new	(	const char *	name,
		int32_t	queue_size,
		int32_t	w,
		int32_t	h
	)

Creates a new Buffer Consumer based on name and common parameters.

Deprecated:: Deprecated since tizen 6.0.

Since (EFL) :: 1.15

Parameters:

[in]	name	The name of Buffer_Queue, this is needed by Consumer and Provider to connect each other.
[in]	queue_size	Size of Queue (If you pass this 0, then default size two(2) is appied)
[in]	w	Width of buffer recommended to provider.
[in]	h	Height of buffer recommended to provider.

Returns:: Ecore_Buffer_Consumer instance or NULL if creation failed.

Since :: 2.4

void ecore_buffer_consumer_provider_add_cb_set	(	Ecore_Buffer_Consumer *	consumer,
		Ecore_Buffer_Consumer_Provider_Add_Cb	func,
		void *	data
	)

Sets a callback for provider connection events.

Deprecated:: Deprecated since tizen 6.0.

Since (EFL) :: 1.15

Parameters:

[in]	consumer	The Ecore_Buffer_Consumer to set callbacks on
[in]	func	The function to call
[in]	data	A pointer to the user data to store.

A call to this function will set a callback on an Ecore_Buffer_Consumer, causing func to be called whenever consumer is connected with provider.

Since :: 2.4

void ecore_buffer_consumer_provider_del_cb_set	(	Ecore_Buffer_Consumer *	consumer,
		Ecore_Buffer_Consumer_Provider_Del_Cb	func,
		void *	data
	)

Sets a callback for provider disconnection events.

Deprecated:: Deprecated since tizen 6.0.

Since (EFL) :: 1.15

[in]	data	A pointer to the user data to store.

A call to this function will set a callback on an Ecore_Buffer_Consumer, causing func to be called whenever consumer is disconnected with provider.
