CSocket Send() timeout question

I am using CSocket in my Windows Mobile program like so:
CSocket *sock;

I send data to a server running on a PC like so:
sock->Send(&cData, nLength);

I have noticed that if the server is down the socket does not time out.

How can I get it to time out after say a few seconds then try again?

You might try to derive from CSocket and and overwrite the OnClose handler function. That function should/might be called if the socket closed in the meantime.

I personally prefer the native socket calls which are more transparent (IMO). As far as I experienced a send call would fail immediately if the server disconnected or was down. But it may depend on the kind of connection and operation system configuration whether the client's TCP/IP subsystem was able to find out that a server was down. If your's is not, you should call select with timeout before any read or write and decide to break if a select for write timeouts.
