It seems like the problem you are trying to solve is to speed up drwing operations in X by eliminating the need to send all of the individual cmds to the Xserver and/or by copying pixmaps over to the server for display. The shared memory extension allows you to create an Ximage data structure in shared memory which can then be accessed directly by the Xserver rather than by copying via the X protocol. You write your changes into the Ximage and then send a command via X protocol to cause the Xserver to update the display using the updated shared memory image. As you can imagine there is quite a bit of speed gain doing things this way. The advantage is as I already said, you gain speed but since the Xserver and the window manager are still in the loop the desktop remains undisturbed. I think you may find that people writing games use this feature. Anyone else have any thoughts or comments ? _______________________________________________ XFree86 mailing list XFree86@xxxxxxxxxxx http://XFree86.Org/mailman/listinfo/xfree86
