XtAppAddBlockHook(3Xt)		 XT FUNCTIONS		XtAppAddBlockHook(3Xt)

NAME
       XtAppAddBlockHook - register a block hook procedure

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

ARGUMENTS
       app_context
		 Specifies the application context.

       proc	 Specifies the block hook procedure.

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.
