The ITraceEventCallback interface is used by ETW to provide information to the relogger as the tracing process starts, ends, and logs events.
The ITraceEventCallback interface has these methods.
|ITraceEventCallback::OnBeginProcessTrace||Indicates that a trace is about to begin so that relogging can be started.|
|ITraceEventCallback::OnEvent||Indicates that an event has been received on the trace streams associated with a relogger.|
|ITraceEventCallback::OnFinalizeProcessTrace||Indicates that a trace is about to end so that relogging can be finalized.|
This interface is not supported on Windows 7 for the IA64 architecture.
