Detailed Description

template<typename _Mutex>

class std::unique_lock< _Mutex >" A movable scoped lock type.

A unique_lock controls mutex ownership within a scope. Ownership of the mutex can be delayed until after construction and can be transferred to another unique_lock by move construction or move assignment. If a mutex lock is owned when the destructor runs ownership will be released.
