Attempts to retrieve a performance measurement log entry from the performance measurement log.
Attempts to retrieve the performance log entry specified by LogEntryKey. If LogEntryKey is
zero on entry, then an attempt is made to retrieve the first entry from the performance log,

then no entry is retrieved and zero is returned. If LogEntryKey is not zero, then the performance
log entry associated with LogEntryKey is retrieved, and the key for the next entry in the log is
returned. If LogEntryKey is the key for the last entry in the log, then the last log entry is
retrieved and an implementation specific non-zero key value that specifies the end of the performance
log is returned. If LogEntryKey is equal this implementation specific non-zero key value, then no entry
is retrieved and zero is returned. In the cases where a performance log entry can be returned,
the log entry is returned in Handle, Token, Module, StartTimeStamp, and EndTimeStamp.
