IDirectFBSurface | GetAccelerationMask

#### Get a mask of drawing functions that are hardware accelerated with the current settings.

DFBResult GetAccelerationMask (
| IDirectFBSurface |  | * | thiz,
| IDirectFBSurface |  | * | source,
| DFBAccelerationMask |  | * | ret_mask
);

If a source surface is specified the mask will also contain accelerated blitting functions. Note that there is no guarantee that these will actually be accelerated since the surface storage (video/system) is examined only when something actually gets drawn or blitted.
