pReadEntry (PVOID) - in/out
For Error Logging, this is a pointer to a LREREQUEST structure.
The caller can specify an event filter that is used to select only entries of a desired class. The format of the event filter is the same as the event notification filter that is described in the LogOpenEventNotification API. The caller also provides an entry key data structure. Entry keys are generated by this API and by the LogWaitEvent API.
Log File searching typically begins at the entry that follows the one that is specified within the event key. The event key is updated as new entries are read. If no event filter is provided, the LogReadEntry API will read the entry that is pointed to by the event key. The caller also has the option of starting a search at the logical beginning of the Log File.
