Winsock problem.
-
Hi, I dont know whether this is the right place for this question, Please excuse if it is not so,. I have just started programming in winsock. How is my server intimated that one of the clients has sent it some data? should I have a loop with the recv(....) function so that it checks continuously for incoming data? Or are there anyother options? (Windows is my OS) Thanks, Deepak Samuel.

Use
accept(). I had a little server application that used the following functions:WSAStartup()
socket()
bind()
listen()
accept() in loop
closesocket()
WSACleanup()

If you want to wade through some stuff, this link http://www.vijaymukhi.com/vmis/vmchap4.htm should show you an easier way using winsock 2 (that won't freeze your application). wWw.KruncherInc.cOm

what kind of sockets are you using? TCP or UDP? There are 4 (as far as I know) ways to get informed about incoming data. these ways are: - blocking sockets (call recv() and what till it returns control to your app) - use select() to check whether there is activity on the socket - use WSAEventSelect() to assign an EVENT to a socket and then wait for the event - use WSAAsyncSelect() to make the socket send window messages when there is activity If you want to create a server which has a main window, then the forth way could be interesting. If your server doesn't have a window: - For servers (TCP) with only few clients or UDP servers you should use way one. - For servers (TCP) with many clients I'd prefer way two (It's also linux compatible :)). I hope I could help.... Don't try it, just do it! ;-)
