XSync() XSync()
Name
XSync - flush the request buffer and wait for all events and errors to be processed by the server.
Synopsis
XSync(display, discard)
Display *display;
int discard;
Arguments
display Specifies a connection to an X server; returned from XOpenDisplay().
discard Specifies whether XSync() discards all events on the input queue. This argument is either True or False.
Description
XSync() flushes the request buffer, then waits until all events and errors resulting from previous calls have been received and processed
by the X server. Events are placed on the input queue. The client's XError routine is called once for each error received.
If discard is True, XSync() discards all events on the input queue (including those events that were on the queue before XSync() was
called).
XSync() is sometimes used with window manipulation functions (by the window manager) to wait for all resulting exposure events. Very few
clients need to use this function.
