What guarantees does X give when it comes to the order of events generated in relation to processing of the requests sent by the client?
(Also, of course: To which degree does various implementations of X actually fulfill these guarantees?) Some specific questions: X events have a "serial" value. I expect that any event delivered by X will reflect the state after the request number "serial" (and all preceding requests) have been processed. Is this correct? Can I also assume that the X event will reflect the state before any requests with a later serial number is processed? (And I assume that "serial" is monotonically increasing, except on wrap-arounds...) Context: Given an application that frequently performs a sequence of XCopyArea() calls on the contents of a window. When this application receives Expose events or GraphicsExpose events, it is necessary for the application to know exactly which XCopyArea calls have taken effect to be able to correctly calculate which area of the window has become invalid. eirik _______________________________________________ [email protected]: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg Your subscription address: [email protected]
