std::lock_g...::lock_guard(3) C++ Standard Libary std::lock_g...::lock_guard(3) NAME std::lock_guard::lock_guard - std::lock_guard::lock_guard Synopsis explicit lock_guard( mutex_type& m ); (1) (since C++11) lock_guard( mutex_type& m, std::adopt_lock_t t ); (2) (since C++11) lock_guard( const lock_guard& ) = delete; (3) (since C++11) Acquires ownership of the given mutex m. 1) Effectively calls m.lock(). 2) Acquires ownership of the mutex m without attempting to lock it. The behavior is undefined if the current thread does not hold a non-shared lock (i.e., a lock acquired by lock, try_lock, try_lock_for, or try_lock_until) on m. 3) Copy constructor is deleted. The behavior is undefined if m is destroyed before the lock_guard object is. Parameters m - mutex to acquire ownership of t - tag parameter used to select non-locking version of the constructor Exceptions 1) Throws any exceptions thrown by m.lock(). 2) Throws nothing. http://cppreference.com 2024.06.10 std::lock_g...::lock_guard(3)
