XtAppAddBlockHook(3)						   XT FUNCTIONS 					      XtAppAddBlockHook(3)

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.

NAME

       XtAppAddActionHook, XtRemoveActionHook - register an action hook procedure

SYNTAX

       XtActionHookId XtAppAddActionHook(app_context, proc, client_data)
	     XtAppContext app_context;
	     XtActionHookProc proc;
	     XtPointer client_data;

       void XtRemoveActionHook(id)
	     XtActionHookId id;

ARGUMENTS

       app_context
		 Specifies the application context.

       proc	 Specifies the action hook procedure.

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

DESCRIPTION

       XtAppAddActionHook adds the specified procedure to the front of a list maintained in the application context. In the future, when an action
       routine is about to be invoked for any widget in this application context, either through the translation manager or via XtCallActionProc,
       the action hohok procedures will be called in reverse order of registration jut prior to invoking the action routine.

       Action hook procedures are removed automatically and the XtActionHookId s destroyed when the application context in which they were added
       is destroyed.

       XtRemoveActionHook removes the specified action hook procedure from the list in which it was registered.
