WebA unique lock is an object that manages a mutex object with unique ownership in both states: locked and unlocked. On construction (or by move-assigning to it), the object acquires a mutex object, for whose locking and unlocking operations becomes responsible. The object supports both states: locked and unlocked. This class guarantees an … WebA recursive mutex is a lockable object, just like mutex, but allows the same thread to acquire multiple levels of ownership over the mutex object. This allows to lock (or try-lock) the mutex object from a thread that is already locking it, acquiring a new level of ownership over the mutex object: the mutex object will actually remain locked owning the thread …

Also, side note: Inserting at the beginning of a std::vector always requires copying/moving the whole vector. That will take a long time very quickly. You should insert only at the end of a std::vector. If you need insertion at the beginning, use std::deque or std::list or insert at the end in reverse and reverse the vector afterwards. how many medals has shaun white won

WebSep 9, 2016 · The standard library provides a mutex class, with the ability to manually lock and unlock it: std::mutex m; m.lock (); // ... m.unlock (); However, the library apparently also recognizes that a common case is just to lock the mutex at some point, and unlock it when leaving a block. For this it provides std::lock_guard and std::unique_lock: WebIn such scenario, one thread will exit without releasing the lock and other threads will remain in waiting. This kind of scenario can happen in case some exception came after locking the mutex. To avoid such scenarios we should use std::lock_guard. std::lock_guard std::lock_guard is a class template, which implements the RAII for mutex.
