XSynchronize() XSynchronize()
Name
XSynchronize - enable or disable synchronization for debugging.
Synopsis
int (*XSynchronize(display, onoff))()
Display *display;
Bool onoff;
Arguments
display Specifies a connection to an X server; returned from XOpenDisplay().
onoff Specifies whether to enable or disable synchronization. You can pass False (normal asynchronous mode) or True (enable synchro-
nization for debugging).
Returns
The previous after function.
Description
XSynchronize() turns on or off synchronous mode for debugging. If onoff is True, it turns on synchronous behavior; False resets the state
to normal mode.
When events are synchronized, they are reported as they occur instead of at some later time, but server performance is many times slower.
This can be useful for debugging complex event handling routines. Under UNIX, the same result can be achieved without hardcoding by set-
ting the global variable _Xdebug to True from within a debugger.
XSynchronize() returns the previous after function.
