After a queue is committed by calling SetupCommitFileQueue, it will begin to process the queued operations. At each step, the queue sends a notification to the callback routine specified in the call to SetupCommitFileQueue.
Following is the syntax that SetupCommitFileQueue uses to send a notification to the callback routine.
MsgHandler( //the specified callback routine
Context, //context used by the callback routine
Notification, //queue notification code
Param1, //additional notification information
Param2 //additional notification information
);
The values of Param1 and Param2 contain additional information relevant to the notification being sent to the callback routine. Each notification, its Param1 and Param2 values, and how the default queue callback routine handles that notification, is described in detail in File Queue Notifications.
