I'm looking for a library to add a socks proxy option to a C/C++ program. What libraries are available for unix and what is the best way to achieve this?

The solution should:

• be considered best practice (safe)
• work in multi-threaded programs with short single-threaded connections
• easy to implement / maintain (if possible)
• work for unix (linux/debian/ubuntu)

Found a lot of information on the internet but nothing specific, and don't know what to use or when to use it.

Answer 1

I do recommend:

• libboost: http://www.boost.org/doc/libs/1_35_0/doc/html/boost_asio/reference/ip__tcp/socket.html
• Qt: http://qt-project.org/doc/qt-5.0/qtnetwork/examples-network.html

Both are multiplatform and very good libraries, but Qt is for GUIs more than a simple library, so think about using libboost for this single purpose.
