Pass parameters to std::thread wrapper

Question

I want to implement a small thread wrapper that provides the information if a thread is still active, or if the thread has finished its work. For this I need to pass the functio

Answer 1

The answer by @O'Neil is correct, but I would like to offer a simple lambda approach, since you've tagged this as C++14.

template
ManagedThread::ManagedThread(Function&& f, Args&&... args):
      mActive(false),
      mThread([&] /*()*/ { // uncomment if C++11 compatibility needed
        mActive = true;
        std::forward(f)(std::forward(args)...);
        mActive = false;
      })
{}

This would eliminate the need for an external function all together.
