Synopsis

Documentation

streamHandler :: Handle -> Priority -> IO (GenericHandler Handle)Source

Create a stream log handler. Log messages sent to this handler will be sent to the stream used initially. Note that the close method will have no effect on stream handlers; it does not actually close the underlying stream.

fileHandler :: FilePath -> Priority -> IO (GenericHandler Handle)Source

Create a file log handler. Log messages sent to this handler will be sent to the filename specified, which will be opened in Append mode. Calling close on the handler will close the file.

data GenericHandler a Source

A helper data type.
