I have discovered that whenever I kill the server process when it is currently connected to a client, this error will occur when I try to restart the server..so I need to change the port that it waits on to get it back up. But thats not viable solution, because clients need to hardcode the port to connect to. What do I do?
bool resume_listening()
{
std::cout << "Listening for new connections..\n";
if ( ::listen( listenSocket, SOMAXCONN ) == SOCKET_ERROR )
{
perror("listen listenSocket");
std::cout << "Error listening on socket\n";
closesocket(listenSocket);
return false;
}
return true;
}
bool create_listen_socket(int port)
{
std::cout << "Creating listener socket..\n";
//create listen socket
listenSocket = socket( AF_INET, SOCK_STREAM, 0 );
if (listenSocket == INVALID_SOCKET) {
perror("create listenSocket");
std::cout << "Unable to create listenSocket\n";
return false;
}
//----------------------
// The sockaddr_in structure specifies the address family,
// IP address, and port of the client to be connected to.
struct sockaddr_in service;
service.sin_family = AF_INET;
service.sin_addr.s_addr = INADDR_ANY;
service.sin_port = htons(port);
// Enable address reuse

int on = 1;
setsockopt( listenSocket, SOL_SOCKET, SO_REUSEADDR, (const char*)&on, sizeof(on) );
//setup
if ( bind(listenSocket, (SOCKADDR*)&service, sizeof(service) ) == SOCKET_ERROR )
{
perror("bind listenSocket");
std::cout << "Unable to bind listenSocket\n";
closesocket(listenSocket);
return false;
}
return resume_listening();
}
