ERROR_SUCCESS on success, or an error code on failure. Possible error codes include the following:

Return code Description
ERROR_NO_DATA
 No performance logs were collected.
ERROR_INVALID_DATA
 Performance logging is not enabled.

Remarks

The performance log is written to the shperf.log file in the Windows directory. If message performance logs are enabled, the message performance log is written to the msgtrace.log file in the Windows directory. If you call StopWatchFlush, you must have permission to create and modify files in the Windows directory.

Calling StopWatchFlush clears the performance logs after writing them to the shperf.log file.

See the StopWatchMode function for a description of the information that is recorded in the performance log.
