// Duplicate the socket to share the same connection across threads.
// In a multithreaded application, each thread should use its own socket object. For example:

// - The main thread can use the original socket for reading.
// - A secondary thread can use a duplicate for writing.
// - Another thread can use a separate duplicate to monitor the connection status.

success = [socket DupSocket: socket_for_monitor];
if (success == NO) {
    NSLog(@"%@",socket.LastErrorText);
    return;

// All three socket objects: socket, socket_for_sending, and socket_for_monitor share the same underlying connection.
