mir_connection_allocate_buffer_gbm

typedef void(* mir_connection_allocate_buffer_gbm) (MirConnection *connection, int width, int height, unsigned int gbm_pixel_format, unsigned int gbm_bo_flags, MirBufferCallback available_callback, void *available_context)

Allocate a MirBuffer via gbm.

The callback will be called when the buffer is available for use. It will be called once when created, and once per every mir_presentation_chain_submit_buffer.

The buffer can be destroyed via mir_buffer_release().

Note

Not all formats or flags are available, and allocations may fail. Be sure to check mir_buffer_is_valid() on the returned buffer.

Parameters

[in]	connection	The connection
[in]	width	Requested buffer width
[in]	height	Requested buffer height
[in]	gbm_pixel_format	The pixel format, one of the GBM_FORMATs
[in]	gbm_bo_flags	The gbm_bo_flags for the buffer.
[in]	available_callback	The callback called when the buffer is available
[in]	available_context	The context for the available_callback
