(This function is part of SDL_net, a separate library from SDL.)


Open a TCP network socket.

Header File

Defined in <SDL_net.h>


TCPsocket SDLNet_TCP_Open(IPaddress *ip);

Function Parameters

IPaddress * ip The address to open a connection to (or to host a server on).

Return Value

(TCPsocket) Returns the newly created socket, or NULL if there was an error.


If ip->host is INADDR_NONE or INADDR_ANY, this creates a local server socket on the given port, otherwise a TCP connection to the remote host and port is attempted. The address passed in should already be swapped to network byte order (addresses returned from SDLNet_ResolveHost() are already in the correct form).


This function is available since SDL_net 2.0.0.
