Member Function Documentation

bind()

fge::net::Socket::Error fge::net::SocketUdp::bind	(	fge::net::Port	port,
		IpAddress const &	address )

Bind the socket to a local address and port.

From MSDN: The bind function associates a local address and port with a socket.

Parameters

port	The local port to bind to
address	The local address to bind to

From MSDN: For a connectionless socket the operation performed by connect is merely to establish a default destination address that can be used on subsequent send and receive calls. Any datagrams received from an address other than the destination address specified will be discarded.

Parameters

remoteAddress	The remote address to connect to
remotePort	The remote port to connect to

Returns

Error::ERR_NOERROR if successful, otherwise an error code
