Function Documentation

fsal_boolean_t fsal_do_log ( fsal_status_t  status)

fsal_do_log: Indicates if an FSAL error has to be traced into its log file in the NIV_EVENT level. (in the other cases, return codes are only logged in the NIV_FULL_DEBUG logging lovel).

Parameters:
status(input),:The fsal status that is to be tested.
Returns:
- TRUE if the error is to be traced.
  • FALSE if the error must not be traced except in NIV_FULL_DEBUG level.
