/**
* soup_address_resolve_async:
* @addr: a #SoupAddress
* @async_context: (allow-none): the #GMainContext to call @callback from
* @cancellable: a #GCancellable object, or %NULL
* @callback: (scope async): callback to call with the result
* @user_data: data for @callback
*
* Asynchronously resolves the missing half of @addr (its IP address
* if it was created with soup_address_new(), or its hostname if it
* was created with soup_address_new_from_sockaddr() or
* soup_address_new_any().)
*
* If @cancellable is non-%NULL, it can be used to cancel the
* resolution. @callback will still be invoked in this case, with a
* status of %SOUP_STATUS_CANCELLED.
*
* It is safe to call this more than once on a given address, from the
* same thread, with the same @async_context (and doing so will not
* result in redundant DNS queries being made). But it is not safe to
* call from multiple threads, or with different @async_contexts, or
* mixed with calls to soup_address_resolve_sync().
