XtAppAddBlockHook(3)		 XT FUNCTIONS		  XtAppAddBlockHook(3)

NAME
       XtAppAddBlockHook, XtRemoveBlockHook - register a block hook procedure

SYNTAX
       XtBlockHookId XtAppAddBlockHook(XtAppContext app_context, XtBlock‚Äź
	      HookProc 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.
