How to use C++ member function in thread pool about thread-pool

[mtrebi]

Hey! I am glad you liked the readme, it took me some time to write it 👍

Regarding your question, yes, there's a way to pass member functions. Your approach doesn't work because the submit function is implemented in such way that the first argument is always the function and the following arguments are the parameters of the function. Probably I could override the submit function or something similar to make it easier...In the meantime, you can solve the issue using std::bind. The idea is basically to create a new function that is simply the function we want to call with the specific object from which we want to call it.

auto func = std::bind(&A::func_1, &objA);
pool.submit(func);

You could do exactly the same using lambda expressions,

pool.submit([&]() {objA.func1(); });

Hope this helps!

Thanks. I will give std::bind a try or use lambda expressions. I will post the results to help answer others visiting your project.

Appreciate your quick reply.

Whenever I have some more time I will try to add an easier way to do it. I am really busy lately...

I tried both bind and lambda approach. Both did not work the way I wanted in my app! So using a C wrapper functions to invoke member functions via the class object. This works for me as I intended.

I tried both options and they worked for me. What do you mean with ¨Both did not work the way I wanted?

Anyway, I am glad you found the solution to your problem 👍
