  * DllMain is the standard entry point call when the DLL is loaded or unloaded.
  *
- * \param[in] module_handle
+ * \param[in] moduleHandle
  *    Handle for this instance of the DLL; same as the module handle.
  *    This handle allows us to get the DLL file name for logging.
  * \param[in] reason
  *    The point in the DLL life cycle at which this call is made. Called "reason code" by Microsoft.
  * \param[in] reserved
  *    No longer reserved, since it contains a point in the thread life cycle.
  *    We aren't using it, though.
