Have a look at the GLX Surface Pool implementation with the Read/Write() hooks in the X11 system module which is in system/x11/glx_surface_pool.c in git master branch. This is basically what you need which differs from any other system module or driver. For the rest you can look at the Davinci driver's OSD Layer and maybe OSD Pool implementation to extract the common parts from the GLX specifics. Let me know if you need more detailed explanations. -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" _______________________________________________ directfb-dev mailing list directfb-dev@directfb.org http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-dev
