Network.TCP

Description

An easy access TCP library. Makes the use of TCP in Haskell much easier. This was originally part of Gray's\/Bringert's HTTP module.

  • Changes by Robin Bate Boerop robin@bateboerop.name: - Made dependencies explicit in import statements. - Removed false dependencies from import statements. - Removed unused exported functions.
  • Changes by Simon Foster: - Split module up into to separate Network.[Stream,TCP,HTTP] modules

Synopsis

Documentation

data Connection Source

The Connection newtype is a wrapper that allows us to make connections an instance of the Stream class, without ghc extensions. While this looks sort of like a generic reference to the transport layer it is actually TCP specific, which can be seen in the implementation of the 'Stream Connection' instance.

Instances

openTCPPort :: String -> Int -> IO ConnectionSource

This function establishes a connection to a remote host, it uses getHostByName which interrogates the DNS system, hence may trigger a network connection.

isConnectedTo :: Connection -> String -> IO BoolSource

Checks both that the underlying Socket is connected and that the connection peer matches the given host name (which is recorded locally).
