* This functions will handle input events on all registered file descriptors.

* - waitForInput - True if we want the function to wait until an event
* appears on a file descriptor we watch, False if we
* want the function to immediately return if there is
* no data available on the file descriptors we watch.
* - inputfd - Extra input file descriptor to watch for input.
* This is only used when called from wevent.c to watch
* on ConnectionNumber(dpy) to avoid blocking of X events
* if we wait for input from other file handlers.
* Output:
* if waitForInput is False, the function will return False if there are no
* input handlers registered, or if there is no data
* available on the registered ones, and will return True
* if there is at least one input handler that has data
* available.
* if waitForInput is True, the function will return False if there are no
* input handlers registered, else it will block until an
* event appears on one of the file descriptors it watches
* and then it will return True.
*
* If the retured value is True, the input handlers for the corresponding file
* descriptors are also called.
*
* Parametersshould be passed like this:
* - from wevent.c:
* waitForInput - apropriate value passed by the function who called us
* inputfd = ConnectionNumber(dpy)
* - from wutil.c:
* waitForInput - apropriate value passed by the function who called us
* inputfd = -1
