basic_deadline_timer::basic_deadline_timer (2 of 7 overloads)

Constructor.

template<
    typename ExecutionContext>
basic_deadline_timer(
    ExecutionContext & context,
    typename constraint< is_convertible< ExecutionContext &, execution_context & >::value >::type  = 0);

This constructor creates a timer without setting an expiry time. The expires_at() or expires_from_now() functions must be called to set an expiry time before the timer can be waited on.

Parameters

context: An execution context which provides the I/O executor that the timer will use, by default, to dispatch handlers for any asynchronous operations performed on the timer.
