##### ip::basic_resolver::async_resolve (6 of 6 overloads)

Asynchronously perform reverse resolution of an endpoint to a list of entries.

    template<
        typename ResolveHandler = DEFAULT>
    DEDUCED async_resolve(
        const endpoint_type & e,
        ResolveHandler && handler = DEFAULT);

This function is used to asynchronously resolve an endpoint into a list of endpoint entries.

###### Parameters

e

  An endpoint object that determines what endpoints will be returned.

handler

  The handler to be called when the resolve operation completes. Copies will be made of the handler as required. The function signature of the handler must be:

      void handler(
        const asio::error_code& error, // Result of operation.
        resolver::results_type results // Resolved endpoints as a range.
      );

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

A successful resolve operation is guaranteed to pass a non-empty range to the handler.
