(Deprecated: Use overload with separate host and service parameters.) Asynchronously perform forward resolution of a query to a list of entries.
template< typename ResolveHandler = DEFAULT> DEDUCED async_resolve( const query & q, ResolveHandler && handler = DEFAULT);
This function is used to asynchronously resolve a query into a list of endpoint entries.
A query object that determines what endpoints will be returned.
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 boost::system::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
A successful resolve operation is guaranteed to pass a non-empty range to the handler.
