DirectFB Reference Manual

GetAccelerationMask

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

GetAccelerationMask (

IDirectFBSurface *thiz

IDirectFBSurface *source

DFBAccelerationMask *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.
