XtRemoveCallback()														XtRemoveCallback()

Name
  XtRemoveCallback - remove a callback from a callback list.

Synopsis
  void XtRemoveCallback(object, callback_name, callback, client_data)
	 Widget object;
	 String callback_name;
	 XtCallbackProc callback;
	 XtPointer client_data;

Inputs
  object    Specifies the object; may be of class Object or any subclass thereof.

  callback_name
	    Specifies the name of the callback list from which the callback is to be removed.

  callback  Specifies the callback procedure which is to be removed.

  client_data
	    Specifies the data which was registered with the specified procedure.

Description
  XtRemoveCallback()  removes  the callback/client_data pair from the callback list named by callback_name of the object object.  If there is
  no entry in the specified callback list that matches both callback and client_data, XtRemoveCallback() returns without generating a warning
  message.

Usage
  Note	that  there is no way to remove all calls to a specified procedure from a callback list.  To remove a procedure from a callback list,
  you must specify the client_data it was registered with.

  If you want to remove several procedure/data pairs from a callback list at the same time, use XtRemoveCallbacks().
