3.3.3 SDLNet_TCP_Accept

TCPsocket SDLNet_TCP_Accept(TCPsocket server)

server

This is the server TCPsocket which was previously created by
SDLNet_TCP_Open.

Accept an incoming connection on the server TCPsocket.
Do not use this function on a connected socket. Server sockets are never connected to a remote host. What you get back is a new TCPsocket that is connected to the remote host.
This is a non-blocking call, so if no connections are there to be accepted, you will get a NULL TCPsocket and the program will continue going.

Returns: a valid TCPsocket on success, which indicates a successful connection has been established. NULL is returned on errors, such as when it's not able to create a socket, or it cannot finish connecting to the originating host and port. There also may not be a connection attempt in progress, so of course you cannot accept nothing, and you get a NULL in this case as well.

// accept a connection coming in on server_tcpsock TCPsocket new_tcpsock; new_tcpsock=SDLNet_TCP_Accept(server_tcpsock); if(!new_tcpsock) { printf("SDLNet_TCP_Accept: %s\n", SDLNet_GetError()); } else { // communicate over new_tcpsock }
