std::mutex::mutex
std::mutex::mutex
constexpr mutex(); | (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).
Exceptions
noexcept
specification: noexcept
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.
