How to get IP address will be used by HTTP in C++

At the client side, when my client machine talks to server, the server
will see the IP address of my machine as part of HTTP request. My
question is how I can programmatically get this IP address which will
be used in HTTP request? I could use gethostname to get IP addresses,
but that is a list. How can I tell which one will be used?

Thanks very much in advance.

There's no such thing as "HTTP" in C++.

At the client side, when my client machine talks to server, the server
will see the IP address of my machine as part of HTTP request. My
question is how I can programmatically get this IP address which will
be used in HTTP request? I could use gethostname to get IP addresses,
but that is a list. How can I tell which one will be used?

That depends on your specific platform. Try a newsgroup that's appropriate
for your operating system, that's oriented towards development topics. This
has nothing to do with C++. You can also implement HTTP in Python and Perl,
for example, and the same question applies.

alt.winsock and alt.winsock programming are probably the more
frequented groups to consult for such things, although traffic isn't
what I'd like it to be.
