This module provides access to the BSD socket interface. This
module is generally more efficient than the
String based network
Socket. For detailed documentation, consult
your favorite POSIX socket reference. All functions communicate
failures by converting the error number to
This module is made to be imported with
Socket like so:
import Network.Socket hiding (send, sendTo, recv, recvFrom) import Network.Socket.ByteString.Lazy import Prelude hiding (getContents)
Send data to a socket
Receive data from a socket
Receive data from the socket. The socket must be in a connected
state. Data is received on demand, in chunks; each chunk will be
sized to reflect the amount of data received by individual
All remaining data from the socket is consumed. When there is no more data to be received, the receiving side of the socket is shut down. If there is an error and an exception is thrown, the socket is not shut down.
Receive data from the socket. The socket must be in a connected state. This function may return fewer bytes than specified. If the received data is longer than the specified length, it may be discarded depending on the type of socket. This function may block until a message arrives.
If there is no more data to be received, returns an empty
Receiving data from closed socket may lead to undefined behaviour.
