NAME

       XtAppAddBlockHook, XtRemoveBlockHook - register a block hook procedure

SYNTAX

       XtBlockHookId XtAppAddBlockHook(XtAppContext app_context, XtBlockHookProc proc, XtPointer
              client_data);

       void XtRemoveBlockHook(XtBlockHookId id);

ARGUMENTS

       app_context
                 Specifies the application context.

       proc      Specifies the block hook procedure.

       num_args  Specifies the application-specific data to be passed to the block hook.

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.

       Block hook procedures are removed automatically and the 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.
