Types of Locks: std::lock_guard
Explore how std::lock_guard simplifies concurrency in C++ by automatically locking and unlocking mutexes following RAII principles. Understand its role in managing shared data safely, reducing deadlock risks, and how its scope limits control the mutex lifetime. This lesson also previews advanced locking mechanisms like std::scoped_lock for atomic mutex locking.
We'll cover the following...
Locks take care of their resource following the RAII idiom. A lock automatically binds its mutex in the constructor and releases it in the destructor; this considerably reduces the risk of a deadlock because the runtime takes care of the mutex.
Locks are available in three different flavors: std::lock_guard for the simple use-cases; std::unique-lock for the advanced use-cases; std::shared_lock is available (with C++14) and can be used to ...
