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 |
Read a SockAddr from the given memory location.
|
|
pokeSockAddr :: Ptr a -> SockAddr -> IO () |
Write the given SockAddr to the given memory location.
|
|
sizeOfSockAddr :: SockAddr -> Int |
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 |
Computes the storage requirements (in bytes) required for a
SockAddr with the given Family.
|
|
withSockAddr :: SockAddr -> (Ptr SockAddr -> Int -> IO a) -> IO a |
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 |
Create a new SockAddr for use with a function requiring a
pointer to a SockAddr and the length of that SockAddr.

what is supported by the operating system.
