Log

Module for logging to Streams.

Initially no stream is present and must be added after creation of class.

Logging to a stream is dependent on the logging level associated with the stream. The levels is in accending order:

• DEBUG

• INFO

• WARN

• ERROR

• FATAL

Logging to the stream will only be done for the associated level and higher levels.

Const

INFO*   = Const.INFO;

WARN*   = Const.WARN;

ERROR*  = Const.ERROR;

FATAL*  = Const.FATAL;

Vars

fh : ADTStream.MemoryStream;

logstreams : ARRAY LOGSIZE OF LogStream;

logs : SHORTINT;

Procedures

Debug

Reference to Format for formatting options.

PROCEDURE Debug*(fmt- : ARRAY OF CHAR; SEQ seq: SYSTEM.BYTE);

Info

PROCEDURE Info*(fmt- : ARRAY OF CHAR; SEQ seq: SYSTEM.BYTE);

Warn

WARN level logging.

PROCEDURE Error*(fmt- : ARRAY OF CHAR; SEQ seq: SYSTEM.BYTE);

Fatal

FATAL level logging.

AddStream
