Defined in header <condition_variable>
enum class cv_status {     no_timeout,     timeout   };		(since C++11)

The scoped enumeration std::cv_status describes whether a timed wait returned because of timeout or not.

std::cv_status is used by the wait_for and wait_until member functions of std::condition_variable and std::condition_variable_any.

Member constants

Name	Explanation
no_timeout	the condition variable was awakened with notify_all, notify_one, or spuriously
timeout	the condition variable was awakened by timeout expiration

See also

wait_for	blocks the current thread until the condition variable is awakened or after the specified timeout duration (public member function of std::condition_variable)
wait_for	blocks the current thread until the condition variable is awakened or after the specified timeout duration (public member function of std::condition_variable_any)
wait_until	blocks the current thread until the condition variable is awakened or until specified time point has been reached (public member function of std::condition_variable)
wait_until	blocks the current thread until the condition variable is awakened or until specified time point has been reached (public member function of std::condition_variable_any)
