Hi, I use the Lock() to get the data pointer of surface, and the data pointer also is as real data pointer in the external graphics controller.
It's normal when i StretchBlit() if i create the "system only" source surface. But if i create the source surface with acceleration, "segmentation fault" happened in context of external graphics controller, so i want to know wether the data pointer of surface could be changed when in operation of "gfxcard" which as StretchBlit(), Blit() and so on ? In my case, i need a static data pointer of surface when it's be created and it's used in context of external graphics controller, someone have any ideas ? Thanks, - Jojo
