Remove a socket from a set of sockets to be checked for available data.
int SDLNet_DelSocket(SDLNet_SocketSet set, SDLNet_GenericSocket sock);
|set||the socket set to remove a socket from.|
|sock||the socket to remove from the set.|
Returns the total number of sockets contained in the set (after
sock's removal), or -1 if
sock was not in the set.
Generally you don't want to call this generic function, but rather the specific, inline function that wraps it: SDLNet_TCP_DelSocket() or SDLNet_UDP_DelSocket().
sock is NULL, nothing is removed from the set; this lets you query the number of sockets currently contained in the set.
This will return -1 if the socket was not found in the set; in such a case, nothing is removed from the set.
This function is available since SDL_net 2.0.0.
