multithreading - Getting user input in C++ without halting the program -

I have a C ++ program that captures the video, and I have a command to update my frame Would like to be able to create line programs, rate, image format etc. on flying

How can I do this without stopping the entire program? I need to be able to wait for user input, but still capture video at the same time. I know that this might include some kind of multi-threading, which I'm totally new, some suggestions / links would be good

Are you developing it for a specific platform Or what does

If you are developing for windows, then you should see the Win32 API, especially on MSDN at beginthread or _beginthreadex

I * am not very familiar with the development of nick, but I believe that is the trick and it can be used in Windows and * nix

Another option would be to use Boost libraries Boost can be used on Windows and * NIX systems Boost Thread Documentation A link to is.

I think drop threads are much easier than WIN32 Threads, and you also have a specific platform API.
