CK_Callback

This is a mixin class. An application class inherits CK_Callback and must provide an implementation for the callback() method. The CK_Callback object is called by the CK_ddEngine if a poll callback has been setup. The poll callback is called by the Chilkat engine on each iteration of the main loop. The reason for creating a polling callback is to provide the application with a way to check for network messages (from DirectPlay for example).

The CK_Callback mixin class may be used for other types of callbacks in the future.
