nana::threads::unique_lock<typename Mutex> Description The class lock_guard maintains the ownership of a mutex object through the lock_guard's object lifetime. Model of None Public base classes None Template Parameters Mutex The type of a mutex object. Typedefs mutex_type The alias type of Mutex. Members unique_lock() The construction. explicit unique_lock(menu_type& m) Locks the mutex. If the mutex object is a non-recursive mutex, it might throw a std::runtime_error if the mutex is obtained the ownership. ~unique_lock() Unlocks the mutex if it owns. void lock() Locks the mutex. bool try_lock() Attempts to obtain the ownership without blocking. If ownership is not obtained, it returns false. bool try_lock_for(std::size_t milliseconds) Attempts to obtain the ownership. It returns false, the waiting is timed out. void unlock() Unlocks the mutex. void swap(unique_lock& u) throw() Swaps two locks. mutex_type * release() throw() Detachs the mutex and returns the address of previous mutex object. operator bool() const throw() Returns true if it owns the ownership of the mutex. mutex_type * mutex() const throw() Returns the address of mutex object.
