See gupnp_service_proxy_action_get_result(); this version takes a #GHashTable for runtime generated parameter lists.
The out_hash needs to be pre-initialized with key value pairs denoting the argument
to retrieve and an empty #GValue initialized to hold the wanted type with g_value_init().

A variant of gupnp_service_proxy_action_get_result() that takes lists of

in out_values must be freed using #g_list_free and each element in it using
#g_value_unset and #g_free.

Prepares action action with parameters in_names and in_values to be
sent off to a remote service later with gupnp_service_proxy_call_action() or
gupnp_service_proxy_call_action_async(). This is mainly useful for language
bindings.
After the action call has finished, the results of the call may be
retrived from the #GUPnPServiceProxyAction by using
gupnp_service_proxy_action_get_result(),
gupnp_service_proxy_action_get_result_list() or
gupnp_service_proxy_action_get_result_hash()
