How does lock_guard work in C++?

Can you explain how lock_guard works in C++?

Sure! lock_guard is a C++ standard library class that provides a convenient RAII-style mechanism for managing mutex locks.

What does RAII stand for?

RAII stands for Resource Acquisition Is Initialization. It ensures that resources are properly released when they go out of scope.

How do I use lock_guard in my code?

You can use lock_guard by including the <mutex> header and creating an instance of lock_guard, passing a mutex to its constructor.

Can you show me a simple code example?

Certainly! Here's a simple example:

#include <iostream>
#include <mutex>

std::mutex mtx;

void safeFunction() {
    std::lock_guard<std::mutex> lock(mtx);
    // critical section
    std::cout << "Thread-safe operation" << std::endl;
}
