Hooks for events in C ++

Question

I am trying to understand event hooks in C ++. I know what an event is, I used a lot of them in Java, C # and Javascript.

I am having problems finding documentation and tutorials on materials such as global interceptors, dll injections, global interceptors without a DLL.

Let's say that I wanted to iterate through the tabis browser in FireFox .. Do I need to hope that FireFox has an API for C ++? Or let's say that I wanted to do something, when the user opens a new tab, will I need to use the hook that FireFox will provide in its API?

The above is just an example, so people know what I'm trying to learn / understand. Am I thinking on the right track?

I saw a message on the forum and have been interested in the last 2 hours. I always say that a complex challenge, or a new challenge, makes a stronger programmer.

Any resources or any help would be greatly appreciated.

Answer 1

C ++ itself has no events or hooks, but many C ++ libraries and frameworks implement them. For an example of a shared event library, see Boost.Signals .

Some of the implementations allow other applications to see their events, but the API is application specific (for example, for Firefox, see XPCOM ).
