How it works...

A mutex is a synchronization primitive that allows us to protect simultaneous access to shared resources from multiple threads. The C++ standard library provides several implementations:

• std::mutex is the most commonly used mutex type; it is illustrated in the preceding code snippet. It provides methods to acquire and release the mutex. lock() tries to acquire the mutex and blocks it if it is not available, try_lock() tries to acquire the mutex and returns it without blocking if the mutex is not available, and unlock() releases the mutex.
• std::timed_mutex is similar to std::mutex but provides two more methods to acquire the mutex using a timeout: try_lock_for() tries to acquire the mutex and returns it if the mutex is not ...
