Hi
I am writing a program for companies who want to plan their workers time. The program communicate with a serverprogram on a Linuxmachine on a TCP/IP-port similar to a www-server and client.

I hope that anyone have a piece of code, with comments that describe how a connection starts, sends and finally closes. It's a twoway-connection, the server can do the same thing with the client.

Thanks Tord

What exactly is the problem?  Are you trying to do it on NT or on Linux?

Its a client-server application. The clients is running Windows NT and connect to the serverprogram on a Unix or Linux machine. It's a demon like the httpd-process.

The serverprogram is responsibli for the database files, locking, user administration and other things.

The client is  graphical interface who presents the result to the user who in turn manipulate the database on the server.

It's working lika a www-connection. The server wait for a connection on a TCP-port and when a client connect to that port i communicate with that client an then close the connection.

But I dont know how to write that piece of code that wait, connect and wait.....

I am looking at Apache sourcecode but it's complex. I hope I can get it clear in this site and the answer show me the piece of code that is neccesary for full functionality.

I suggest you find a good reference about socket programming.  I can refer you to some "winsock" sites (the windows implementation of sockets, very similar to the unix "berkley" sockets if you ignore the MS additions):
  http://www.sockets.com
  http://www.winsock.com
  http://www.goodnet.com/~esnible/winsock.html

In general, check the listen() and accept() functions.
