Question

Let’s say, that I have a program code like this:

    #include <iostream>  
    #include <Windows.h>

    #include <tbb/tbb.h>


    void SomeFunction()
    {
            // do something
    }        

    void MyThread(int arg)
    {
        std::cout << "This is a thread function\n" << std::endl;

        for (int i = 0; i < 10000; i++)
        {
            arg++;
            Sleep(1);
        }

            SomeFunction();
    }

    int main ()
    {
        tbb::tbb_thread pMyThread = tbb::tbb_thread(MyThread, 3);

        pMyThread.join();

        return 0;
    }

From the above we can see that main() is calling MyThread() on a different thread pMyThread. And MyThread() is calling SomeFunction(). Now, will SomeFunction() (or any other function which is called by MyThread()) be executed on pMyThread too? Thanks.

Answer 1

Yes, any function call issued from a thread’s main function will exist on that thread’s private stack.
