constexpr mutex() noexcept; | (1) | (since C++11) |
mutex( const mutex& ) = delete; | (2) | (since C++11) |
(none).
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.
