CCriticalSection criticalSection; // Lock the critical section criticalSection.Lock(); // Perform some operations that must only be executed by one thread at a time // Unlock the critical section criticalSection.Unlock();
void ThreadFunction(CCriticalSection& criticalSection) { // Lock the critical section criticalSection.Lock(); // Perform some operations that must only be executed by one thread at a time // Unlock the critical section criticalSection.Unlock(); } void main() { CCriticalSection criticalSection; // Launch multiple threads that will use the critical section std::thread thread1(ThreadFunction, std::ref(criticalSection)); std::thread thread2(ThreadFunction, std::ref(criticalSection)); std::thread thread3(ThreadFunction, std::ref(criticalSection)); // Wait for all threads to complete thread1.join(); thread2.join(); thread3.join(); }In this example, we create a function that accepts an instance of CCriticalSection as a reference. We then launch multiple threads that call this function and pass in the same instance of CCriticalSection. Each thread will lock the critical section before performing some operations that must only be executed by one thread at a time, and then unlocking the critical section. CCriticalSection Unlock is part of the ATL (Active Template Library) package library, which provides a set of template-based C++ classes that simplify the development of COM (Component Object Model) objects.
