DESCRIPTION

26       XtAppAddBlockHook registers the specified procedure and returns an
27       identifier for it.  The hook is called at any time in the future when
28       the Intrinsics are about to block pending some input.
29
30       Block hook procedures are removed automatically and the XtBlockHookId
31       is destroyed when the application context in which they were added is
32       destroyed.
33
34       XtRemoveBlockHook removes the specified block hook procedure from the
35       list in which it was registered.
