C++11/C++14 Thread 2. Debugging with Visual Studio 2020

"If you're an experienced C++ programmer and are anything like me, you initially approached C++11 thinking, "Yes, yes, I get it. It's C++, only more so." But as you learned more, you were surprised by the scope of the changes. auto declarations, range-based for loops, lambda expressions, and rvalue references change the face of C++, to say nothing of the new concurrency features. And then there are the idiomatic changes. 0 and typedefs are out, nullptr and alias declarations are in. Enums should now be scoped. Smart pointers are now preferable to built-in ones. Moving objects is normally better than copying them.
- Effective Modern C++ by Scott Meyers

In this section, I'll just introduce Parallel Diagnostic Tools (Concurrency Runtime).

The tool has thress major features: Debugging, Profiling, and Event Tracing.

The Visual Studio debugger includes the Parallel Stacks window, Parallel Tasks window, and Parallel Watch window.

The coverage for the other concurrency debugging will be deferred to documents from MS such as Walkthrough: Debugging a Parallel Application.

We can use parallel stack feature, after starting the debugging. From top menu "Debug", then choose Windows, we have bunch of options including "Parellel Stacks":

Before we constructing any thread, we get this:

The picture below is when we are in the thread function:

If we want to see more such as external call stacks, we can right click and select "Show External Code", then we get:
