Date: Sat, 18 May 2002 17:40:53 +0300 From: Mike Gorchak <mike@malva.ua> Subject: New QNX patches - Added more error check to avoid SEGFAULTS; - Fixed bug in update function for SDL_HWSURFACE. BTW: update is much faster than before. - Added checks for SDL_HWSURFACE flag, chosen bpp must be equal to desktop bpp for SDL_HWSURFACE. - Fixed overlay bug, no more SEGFAULTS.
