Detailed Description

Class representing an incident, an occurance out of the ordinary, that happened on the master.

The event is used to inform the slave that something out of the ordinary happened on the master that might cause the database to be in an inconsistent state.

Incident event format

Symbol	Format	Description
INCIDENT	2	Incident number as an unsigned integer
MSGLEN	1	Message length as an unsigned integer
MESSAGE	MSGLEN	The message, if present. Not null terminated.
