Re: Retrieving remote IP address

Scott,

Our GUI package (which the client and server programs are part of) was not 
made in-house, so I don't think I could follow this route.

Even if I had any experience with sockets...  I do have your excellent 
tutorial on my pc for some light reading in-between development ;-)

Thanks,

When the listener program calls the accept() API, the 2nd parameter to 
accept() is a sockaddr data structure that will contain the IP address of 
the socket that has connected to it.

You can also retrieve this information later by passing the socket 
descriptor that's connected to the remote computer to the getpeername() 
API.

The IP address that these APIs return will be in binary format (i.e., 
x'7F000001' instead of 127.0.0.1) but you can convert it to human-readable 

("dotted") format using the inet_ntoa() API.
