- * If the DLL is being used in a WiX MSI environment, LogResult() will
- * route any log messages to the MSI log file via WcaLog() or WcaLogError().
- *
- * If the DLL is NOT being used in a WiX MSI environment, LogResult() will
- * route any log messages to stdout or stderr.
- *
- * If the result is an error code, LogResult will attempt to gather a
- * text version of the error code and place it in the log. For example,
- * if the error code means ERROR_FILE_NOT_FOUND, it will look up the appropriate
- * message ( via FormatMessage() ) and add "The system cannot find the file specified."
