std::condition_variable voidwait(std::unique_lock<std::mutex>&lock); (1)(C++11 起) template<classPredicate> voidwait(std::unique_lock<std::mutex>&lock, Predicate pred); (2)(C++11 起) wait导致当前线程阻塞直至条件变量被通知,或虚假唤醒发生。可以提供pred以检测虚假唤醒。

其中std::condition_variable 仅支持 std::unique_lock<std::mutex> 类型作为互斥量。 std::condition_variable_any 可以支持任意基本可锁定(BasicLockable)类型作为互斥量,例如 [C++14]std::shared_lock,但也就意味着它的效率低于 std::condition_variable。
Defined in header <condition_variable> class condition_variable_any; (since C++11) 大condition_variable_any类是std::condition_variable.鉴于std::condition_variable只在std::unique_lock<std::mutex>,,,condition_variable_any可以对满足BasicLockable所需经费。
