-
- Remember that Xlib is asynchronous. The error can only be detected on the
- server and is returned like an event.
-
- When debugging in X run in synchronous mode by calling
- XSynchronize(display, True)
- so that your errors will be reported immediately after the program issues
- the request to XCopyArea.
-
- NB. Your question would have been answered quicker in comp.windows.x, hence
- the Followup-To.
