As a general rule, check the documentation of your compiler or your OS whenever you want to do something relating to your OS or your hardware. Or else try your favorite search engine: ususally that takes less time than explaining what you want at a forum like this.

In case of GCC, since it's open source, and multiplatform, chances are there's little documentation from the compiler itself - but there will be plenty of information on the web. Just search for it, like this: https://www.google.com/search?q=GCC+Windows+key+event&rlz=1C1GCEU_deCH819CH819&oq=GCC+Windows+key+event&aqs=chrome..69i57.13943j0j8&sourceid=chrome&ie=UTF-8

There is no "one standard way" to do that in C: even kbhit is not a standard method, it's specific to one compiler / library combination - specifically Borland.

You will have to identify the equivalent (if it exists, it doesn't have to) for the OS and libraries you are targetting.
