If you can also specify the channel mask for clearing each buffer, you'd probably want something like: clear(uint numSurfaces, pipe_surface **surfaces, const uint *masks) huh? -Brian ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
