 #   L_ERR (-1)   - used if the error doesn't cause system malfunctioning.

 #   L_WARN (1)   - used to write warning messages.

 #   L_NOTICE (2) - used to report unusual situations.

 #   L_INFO (3)   - used to write informational messages.

 #   L_DBG (4)    - used to write messages for debugging.
