Defined in header <condition_variable>
enum class cv_status {

    timeout     = 0,
    no_timeout  = 1

};
 (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 methods of std::condition_variable and std::condition_variable_any.

Member constants

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