/**
Attempts to retrieve a performance measurement log entry from the performance measurement log.
It can also retrieve the log created by StartPerformanceMeasurement and EndPerformanceMeasurement,
and then assign the Identifier with 0.
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,
and the key for the second entry in the log is returned. If the performance log is empty,
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, EndTimeStamp and Identifier.
If LogEntryKey is not a valid log entry key for the performance measurement log, then ASSERT().
If Handle is NULL, then ASSERT().
If Token is NULL, then ASSERT().
If Module is NULL, then ASSERT().
If StartTimeStamp is NULL, then ASSERT().
If EndTimeStamp is NULL, then ASSERT().
If Identifier is NULL, then ASSERT().
@param LogEntryKey On entry, the key of the performance measurement log entry to retrieve.
0, then the first performance measurement log entry is retrieved.
On exit, the key of the next performance log entry.
@param Handle Pointer to environment specific context used to identify the component
being measured.
@param Token Pointer to a Null-terminated ASCII string that identifies the component
being measured.
@param Module Pointer to a Null-terminated ASCII string that identifies the module
being measured.
@param StartTimeStamp Pointer to the 64-bit time stamp that was recorded when the measurement
was started.
@param EndTimeStamp Pointer to the 64-bit time stamp that was recorded when the measurement
was ended.
@param Identifier Pointer to the 32-bit identifier that was recorded.
@return The key for the next performance log entry (in general case).
