/*
* Protocol testing for XISelectEvents request.
*
* Test approach:
*
* Wrap XISetEventMask to intercept when the server tries to apply the event
* mask. Ensure that the mask passed in is equivalent to the one supplied by
* the client. Ensure that invalid devices and invalid masks return errors
* as appropriate.
*
* Tests included:
* BadValue for num_masks < 0
* BadWindow for invalid windows
* BadDevice for non-existing devices
* BadImplemenation for devices >= 0xFF
* BadValue if HierarchyChanged bit is set for devices other than
* XIAllDevices
* BadValue for invalid mask bits
* Sucecss for excessive mask lengths
*
