Receiving Notifications for Actions on a File

After establishing notification on a c-tree data file, use the ctSysQueueRead() function to read notification messages from a system queue. Non-transaction ISAM updates are immediately processed and placed into the system queue by the notify system. Transaction (including pre-image) updates are not processed until they are committed. The following sections discuss the format of a notification message and how to read notification messages returned by ctSysQueueRead().
