std::mutex::mutex (3) - Linux Man Pages

std::mutex::mutex: std::mutex::mutex

NAME

std::mutex::mutex - std::mutex::mutex

Synopsis


constexpr mutex() noexcept; (1) (since C++11)
mutex( const mutex& ) = delete; (2) (since C++11)


1) Constructs the mutex. The mutex is in unlocked state after the constructor completes.
2) Copy constructor is deleted.

Parameters


(none)

Notes


Because the default constructor is constexpr, static mutexes are initialized as part of static_non-local_initialization, before any dynamic non-local initialization begins. This makes it safe to lock a mutex in a constructor of any static object.
