std::condit...variable_any(3) C++ Standard Libarystd::condit...variable_any(3) NAME std::condition_variable_any - std::condition_variable_any Synopsis Defined in header <condition_variable> class condition_variable_any; (since C++11) The condition_variable_any class is a generalization of std::condi- tion_variable. Whereas std::condition_variable works only on std::unique_lock<std::mutex>, condition_variable_any can operate on any lock that meets the Basi- cLockable requirements. See std::condition_variable for the description of the semantics of condition variables. The class std::condition_variable_any is a StandardLayoutType. It is not CopyConstructible, MoveConstructible, CopyAssignable, or MoveAssign- able. If the lock is std::unique_lock<std::mutex>, std::condition_variable may provide better performance. Member functions constructor constructs the object (public member function) destructor destructs the object (public member function) operator= not copy-assignable [deleted] (public member function) Notification notify_one notifies one waiting thread (public member function) notify_all notifies all waiting threads (public member function) Waiting wait blocks the current thread until the condition variable is woken up (public member function) blocks the current thread until the condition variable is woken up or wait_for after the specified timeout duration (public member function) blocks the current thread until the condition variable is woken up or wait_until until specified time point has been reached (public member function) Notes std::condition_variable_any can be used with std::shared_lock in or- der to wait on a std::shared_mutex in shared ownership mode. A possible use for std::condition_variable_any with custom Lockable types is to provide convenient interruptible waits: the custom lock operation would both lock the associated mutex as expected, and also perform the necessary setup to notify this condition variable when the interrupting signal is re- ceived.^[1] See also condition_variable provides a condition variable associated with a std::unique_lock (C++11) (class) External links 1.
