What are these functions called and how to implement they?

I saw these functions in some projects. For example: in Dagon
(https://gecko0307.github.io/dagon/) there are functions like
onKeyDown. This function doesn't need to call - it checks pressed
keys every time. Or Update in Unity (game engine). It doesn't
need to call, but it executes itself every frame.
Okay, maybe it sounds confusing. I just want to understand how to
implement functions that wait for events and execute code inside
the function. Something like this:
void onKeyPressed(int key) {
//the code to be executed if a key has been pressed
}
