To Request Notification of Reload Events

If you use DtDbLoad() in a long-lived application, it must dynamically reload the database whenever it is modified.

1. Use the DtDbReloadNotify()function to request notification of reload events.

   /* Notice changes to the database without needing to restart
   	 application */
   
     	DtDbReloadNotify(DbReloadCallbackProc, callback_proc,
   	 	XTPointer, client_data);

   Supply a callback that:

   • Destroys cached database information held by the application

   • Calls the DtDbLoad() function again

Callback_proc cleans up any cached database information your application is holding and then invokes DtDbLoad(). Client_data may be used to pass additional client information to the callback routine.
