	SocketServer (SocketDescriptor &socket)
	Build a SocketServer from a SocketDescriptor (already created with SocketDescriptor::create)
Result	close ()
	Calls SocketDescriptor::close.
Result	bind (SocketIPAddress nativeAddress)
	Binds this socket to a given address / port combination.
Result	listen (uint32_t numberOfWaitingConnections)
	Start listening for incoming connections at a specific address / port combination (after bind)
Result	accept (SocketFlags::AddressFamily addressFamily, SocketDescriptor &newClient)
	Accepts a new client, blocking while waiting for it.

Detailed Description

Use a SocketDescriptor as a Server (example TCP or UDP Socket Server).

Example:

    SocketDescriptor serverSocket;
    SocketServer     server(serverSocket);
 
    // Look for an available port
    constexpr int    tcpPort       = 5050;
    const StringView serverAddress = "::1"; // or "127.0.0.1"
    SocketIPAddress  nativeAddress;
    SC_TRY(nativeAddress.fromAddressPort(serverAddress, tcpPort));
    SocketFlags::AddressFamily family = nativeAddress.getAddressFamily();
 
    // Create socket and start listening
    SC_TRY(serverSocket.create(family)); // By default creates a TCP Server
 
    // [Alternatively] Create an UDP socket instead
    // SC_TRY(serverSocket.create(family, SocketFlags::SocketDgram, SocketFlags::ProtocolUdp));
 
    SC_TRY(server.bind(nativeAddress)); // Bind the socket to the given address
    SC_TRY(server.listen(1));           // Start listening (skip this for UDP sockets)
 
    // Accept a client
    SocketDescriptor acceptedClientSocket;
    SC_TRY(server.accept(family, acceptedClientSocket));
    SC_TRY(acceptedClientSocket.isValid());
 
    // ... Do something with acceptedClientSocket

Constructor & Destructor Documentation

SocketServer()

SC::SocketServer::SocketServer ( SocketDescriptor & socket )

inline

Build a SocketServer from a SocketDescriptor (already created with SocketDescriptor::create)

Parameters

socket

A socket descriptor created with SocketDescriptor::create to be used as server

Member Function Documentation

accept()

Result SC::SocketServer::accept ( SocketFlags::AddressFamily addressFamily, SocketDescriptor & newClient )

nodiscard

Accepts a new client, blocking while waiting for it.

Parameters

[in]	addressFamily	The address family of the SocketDescriptor that will be created
[out]	newClient	The SocketDescriptor that will be accepted

Returns

Valid Result if the socket has been successfully accepted

bind()

Result SC::SocketServer::bind ( SocketIPAddress nativeAddress )

nodiscard

Binds this socket to a given address / port combination.

Parameters

nativeAddress

The interface ip address and port to start listening to

Returns

Valid Result if this socket has successfully been bound

close()

Result SC::SocketServer::close ( )

nodiscard

Calls SocketDescriptor::close.

Returns

The Result of SocketDescriptor::close

listen()

Result SC::SocketServer::listen ( uint32_t numberOfWaitingConnections )

nodiscard

Start listening for incoming connections at a specific address / port combination (after bind)

Parameters

numberOfWaitingConnections

How many connections can be queued before accept

Returns

Valid Result if this socket has successfully been put in listening mode

Note

UDP socket cannot be listened. TCP socket need a successful SocketServer::bind before SocketServer::listen
