DESCRIPTION
XtAppAddBlockHook registers the specified procedure and returns an
identifier for it. The hook is called at any time in the future when the
Intrinsics are about to block pending some input.

XtBlockHookId is
destroyed when the application context in which they were added is destroyed.
XtRemoveBlockHook removes the specified block hook procedure from the
list in which it was registered.
