cogl_buffer_get_size

Retrieves the size of buffer.

cogl_buffer_get_update_hint

Retrieves the update hints set using cogl_buffer_set_update_hint().

cogl_buffer_map

Maps the buffer into the application address space for direct access. This is equivalent to calling cogl_buffer_map_range() with zero as the offset and the size of the entire buffer as the size.

cogl_buffer_map_range

Maps a sub-region of the buffer into the application’s address space for direct access.

cogl_buffer_set_data

Updates part of the buffer with new data from data. Where to put this new data is controlled by offset and offset + data should be less than the buffer size.

cogl_buffer_set_update_hint

Sets the update hint on a buffer. See CoglBufferUpdateHint for a description of the available hints.

cogl_buffer_unmap

Unmaps a buffer previously mapped by cogl_buffer_map().
