Description

A module containing semi-public Network.Socket internals. Modules which extend the Network.Socket module will need to use this module while ideally most users will be able to make do with the public interface.

peekSockAddr :: Ptr SockAddr -> IO SockAddr Source

Read a SockAddr from the given memory location.

pokeSockAddr :: Ptr a -> SockAddr -> IO () Source

Write the given SockAddr to the given memory location.

sizeOfSockAddr :: SockAddr -> Int Source

Computes the storage requirements (in bytes) of the given SockAddr. This function differs from sizeOf in that the value of the argument is used.

sizeOfSockAddrByFamily :: Family -> Int Source

Computes the storage requirements (in bytes) required for a SockAddr with the given Family.

withSockAddr :: SockAddr -> (Ptr SockAddr -> Int -> IO a) -> IO a Source

Use a SockAddr with a function requiring a pointer to a SockAddr and the length of that SockAddr.

withNewSockAddr :: Family -> (Ptr SockAddr -> Int -> IO a) -> IO a Source

Create a new SockAddr for use with a function requiring a pointer to a SockAddr and the length of that SockAddr.
