Name

SDLNet_DelSocket -- remove a socket from a socket set.

Synopsis

#include "SDL_net.h"

int SDLNet_DelSocket(SDLNet_SocketSet set, SDLNet_GenericSocket sock);
int SDLNet_TCP_DelSocket(SDLNet_SocketSet set, TCPsocket sock);
int SDLNet_UDP_DelSocket(SDLNet_SocketSet set, UDPsocket sock);

set is the socket set to remove this socket from.

sock is the socket to remove from the socket set.

Description

SDLNet_DelSocket removes a socket from a socket set. Use this before closing a socket that you are watching with a socket set. This doesn't close the socket.

Return Value

Returns the number of sockets used in the set on success. -1 is returned on errors.

Example

// remove two sockets from a socket set
//SDLNet_SocketSet set;
//UDPsocket udpsock;
//TCPsocket tcpsock;
int numused;

numused = SDLNet_UDP_DelSocket(set, udpsock);
if (numused == -1) {
    printf("SDLNet_DelSocket: %s\n", SDLNet_GetError());
    // perhaps the socket is not in the set
}
numused = SDLNet_TCP_DelSocket(set,tcpsock);
if (numused == -1) {
    printf("SDLNet_DelSocket: %s\n", SDLNet_GetError());
    // perhaps the socket is not in the set
}
