I need to write my own or use already written thread's pool in C++ with priorities. Boost threadpool is too complicated. Please, advice me one.
If you have a basic understanding of how to write a simple threadpool with std::queue, change std::queue to std::priority_queue and you will get a threadpool with priorities

I have a few threads in my program - run on Windows and write in C++.
How can I know in the end of the running how much CPU time is used by all or one of them?

Yes. As long as none of your threads do a write
i.e. Construct the data structure in memory
Use as many threads to find/read as you require.
If the leaf needs altering put a mutex there.

How do you declare an interface in C++?
Hi,
What's the preferable way to create single interface and multiple implementations in c++?
For example, I'd like to implement kqueue for mac and epoll for linux and share the interface.
Thank you
The Strategy Pattern is probably what you are looking for.
The Abstract Factory Pattern can help you fill in the right implementation when starting up.

I just came across a new term: thread pool. I don't know what it is, can any ody offer some information about this?
What it is a thread pool and how it is implemented?
Is a thread pool just a collection of threads?
ThreadPool is basically collection of threads. Whenever a task is assigned to the threadpool, the available thread accepts the task and executes it.
The advantages of thread pool is to control the threads creation\destruction and also, optimize the thread usage.
Thread Pool concept is not the C++ language feature. There are many custom implementation of thread Pool. ( Using different strategies).
