Description

The Network.BSD module defines Haskell bindings to network programming functionality (mostly network database operations) provided by BSD Unix derivatives.

NOTE: Some of the types are reexported from Network.Socket in order to make the network-bsd API self-contained.

Windows compatibility

The following functions are not exported by Network.BSD on the Windows platform:

getHostEntries, setHostEntry, getHostEntry, endHostEntry
getServiceEntries, getServiceEntry, setServiceEntry, endServiceEntry
getProtocolEntries, setProtocolEntry, getProtocolEntry, endProtocolEntry
getNetworkByName, getNetworkByAddr, getNetworkEntries, setNetworkEntry, getNetworkEntry, endNetworkEntry
