Hi,
I read the following code which open a server socket for client
request.
However, i would like to know how can I change it so that i just
listen for client requestfor 10 seconds, after that, it bows out?
Code:
// Create socket for listening for client connection requests.
listenSocket = socket(AF_INET, SOCK_STREAM, 0);
if (listenSocket < 0) {
std::cout << "cannot create listen socket";
return;
}
// Bind listen socket to listen port. First set various fields in
// the serverAddress structure, then call bind().
// htonl() and htons() convert long integers and short integers
// (respectively) from host byte order (on x86 this is Least
// Significant Byte first) to network byte order (Most Significant
// Byte first).
serverAddress.sin_family = AF_INET;
serverAddress.sin_addr.s_addr = htonl(INADDR_ANY);
serverAddress.sin_port = htons(listenPort);
if (bind(listenSocket,
(struct sockaddr *) &serverAddress,
sizeof(serverAddress)) < 0) {
std::cout << "cannot bind socket";
return;
}
// Wait for connections from clients.
// This is a non-blocking call; i.e., it registers this program with
// the system as expecting connections on this socket, and then
// this thread of execution continues on.
listen(listenSocket, 10);
int count = 0;
while (1) {
std::cout << "Waiting for TCP connection on port " << listenPort
<< " ...\n";
// Accept a connection with a client that is requesting one. The
// accept() call is a blocking call; i.e., this thread of
// execution stops until a connection comes in.
// connectSocket is a new socket that the system provides,
// separate from listenSocket. We *could* accept more
// connections on listenSocket, before connectSocket is closed,
// but this program doesn't do that.
clientAddressLength = sizeof(clientAddress);
connectSocket = accept(listenSocket,
(struct sockaddr *) &clientAddress,
&clientAddressLength);
if (connectSocket < 0) {
std::cout << "cannot accept connection ";
return;
}
Thank you.
