unsigned int ecore_buffer_flags_get ( Ecore_Buffer * buf )

Return flags of given Ecore_Buffer.

Since :: 2.4

Parameters:

[in] buf The Ecore_Buffer

Returns:: The flags of given Ecore_Buffer.

NOTE: Not Defined yet.

Ecore_Buffer_Format ecore_buffer_format_get ( Ecore_Buffer * buf )

Return format of given Ecore_Buffer.

Since :: 2.4

Parameters:

[in] buf The Ecore_Buffer

Returns:: The format of given Ecore_Buffer.

return value can be one of those pre-defined value such as ECORE_BUFFER_FORMAT_XRGB8888.

void ecore_buffer_free ( Ecore_Buffer * buf )

Free the given Ecore_Buffer.

Since :: 2.4

Parameters:

[in] buf The Ecore_Buffer to free

void ecore_buffer_free_callback_add	(	Ecore_Buffer *	buf,
		Ecore_Buffer_Cb	func,
		void *	data
	)

Set a callback for Ecore_Buffer free events.

Since :: 2.4

Parameters:

[in]	buf	The Ecore_Buffer 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, causing func to be called whenever buf is freed.

See also:: ecore_buffer_free_callback_remove()

[in]	func	The function to remove
[in]	data	A pointer to the user data to remove

See also:: ecore_buffer_free_callback_add()

Returns:: EINA_TRUE if backend has been correctly registered, EINA_FALSE otherwise.

Eina_Bool ecore_buffer_shutdown ( void )

Shut down the Ecore_Buffer system.

Since :: 2.4

Returns:: EINA_TRUE on success, EINA_FALSE otherwise.

See also:: ecore_buffer_init()
