Hello all,

Say I wanted to intercept all X11 events, using an LD_PRELOAD method.
Assume that _everything_ is dynamically linked.

If I redefine XSendEvent(), should I preload this into the window manager,
or into the X server itself? If XSendEvent() is not the function I should
intercept, then what should I intercept?


I guess these questions boil down to two questions:
        Who generates XEvents -- the window manager, the X server, or both?
and,
        When generating XEvents, does the source use XSendEvent()?


Thanks a lot,
