[header][Multi-threading] mutex (C++11)

*[header][Multi-threading] mutex (C++11)

 

<mutex>

Mutex

Header with facilities that allow mutual exclusion (mutex) of concurrent execution of critical sections of code, allowing to explicitly avoid data races.

It contains mutex types, lock types and specific functions:

• Mutex types are lockable types used to protect access to a critical section of code: locking a mutex prevents other threads from locking it (exclusive access) until it is unlocked: mutex, recursive_mutex, timed_mutex, recursive_timed_mutex.
• Locks are objects that manage a mutex by associating its access to their own lifetime: lock_guard, unique_lock.
• Functions to lock mutiple mutexes simultaneously (try_lock, lock) and to directly prevent concurrent execution of a specific function (call_once).
