This -- method is only exported for implementing extension libraries. -- -- The function shall yield the values of constants like -- SOCK_STREAM, SOCK_DGRAM etc. typeNumber :: Type t => t -> CInt -- | The Protocol determines the transport protocol to use. -- -- Use Default to let the operating system choose a transport -- protocol compatible with the socket's Type. class Protocol p -- | This number designates this Protocol on the specific platform. -- This method is only exported for implementing extension libraries. -- -- The function shall yield the values of constants like -- IPPROTO_TCP, IPPROTO_UDP etc. protocolNumber :: Protocol p => p -> CInt -- | Creates a new socket. -- -- Whereas the underlying POSIX socket operation takes 3 parameters, this -- library encodes this information in the type variables.
