Hash functions are exposed as objects in CNG, but because the API needs to be accessible from kernel-mode code (which is mostly written in C), it takes a bit of up-front work to put the object back together. As I mentioned in the introduction, algorithm providers and hash functions are...

For instance, without that line, each reference to cout would have to be written as std::cout. The using statement is added to make the code look more clean. The cout keyword is used to print to standard output in C++. The << operator tells the compiler to send whatever is to the ...
P0515R3 C++20 introduces the <=> three-way comparison operator, also known as the "spaceship operator". Visual Studio 2019 version 16.0 in /std:c++latest mode introduces partial support for the operator by raising errors for syntax that's now disallowed. For example, the following code ...

void FreeFuncInt(int value) { cout << "FreeCallback " << value << endl; }To bind the free function to a delegate, create a DelegateFree1<int> instance using MakeDelegate(). The DelegateFree template argument is the int function parameter. MakeDelegate() returns a DelegateFree1<int> ...

that is, m_lockLineItems is acquired followed by m_lockObjectStatus. This is a design pattern known as lock hierarchy. You can actually write code to enforce this, such that if you try to take a lock that violates the hierarchy, the application can throw an exception instead of deadlock...
