- * cairo_quartz_surface_create_for_data
- * @data: a pointer to a buffer supplied by the application in which

- *     kind of variable, (for example, a pointer returned by malloc).
- * @format: format of pixels in the surface to create
- * @width: width of the surface, in pixels
- * @height: height of the surface, in pixels
- *
- * Creates a Quartz surface backed by a CGBitmap.  The surface is
- * created using the Device RGB (or Device Gray, for A8) color space.
- * All Cairo operations, including those that require software
- * rendering, will succeed on this surface.
- *
- * Return value: the newly created surface.
