(Deprecated: Use overload with separate host and service parameters.) Asynchronously perform forward resolution of a query to a list of entries.
template< typename ResolveToken = DEFAULT> DEDUCED async_resolve( const query & q, ResolveToken && token = DEFAULT);
This function is used to asynchronously resolve a query into a list of endpoint entries. It is an initiating function for an asynchronous operation, and always returns immediately.
A query object that determines what endpoints will be returned.
token that will be used to produce a completion handler,
which will be called when the resolve completes. Potential completion
yield_context, or a function
object with the correct completion signature. The function signature
of the completion 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 completion 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.
