basic_waitable_timer::async_wait

Start an asynchronous wait on the timer.

template<
    typename WaitHandler>
DEDUCED async_wait(
    WaitHandler && handler);

This function may be used to initiate an asynchronous wait against the timer. It always returns immediately.

For each call to async_wait(), the supplied handler will be called exactly once. The handler will be called when:

Parameters

handler

The handler to be called when the timer expires. Copies will be made of the handler as required. The function signature of the handler must be:

void handler(
  const std::error_code& error // Result of operation.
);

Regardless of whether the asynchronous operation completes immediately or not, the handler will not be invoked from within this function. Invocation of the handler will be performed in a manner equivalent to using post.
