Description

The Network.BSD module defines Haskell bindings to network programming functionality provided by BSD Unix derivatives.

Host names

type HostName = String Source

getHostName :: IO HostName Source

Calling getHostName returns the standard host name for the current processor, as set at boot time.

data HostEntry Source

Constructors HostEntry hostName :: HostName hostAliases :: [HostName] hostFamily :: Family hostAddresses :: [HostAddress] Instances Read HostEntry Show HostEntry Typeable HostEntry Storable HostEntry

getHostByName :: HostName -> IO HostEntry Source

Resolve a HostName to IPv4 address.

getHostByAddr :: Family -> HostAddress -> IO HostEntry Source

Get a HostEntry corresponding to the given address and family. Note that only IPv4 is currently supported.

hostAddress :: HostEntry -> HostAddress Source

getHostEntries :: Bool -> IO [HostEntry] Source
