Missing user data in callbacks

[sergico]

More than an issue this is a question.

• Is there a way to pass some custom data to a request and get it back in the callback, the same way it works for the original C based lib c-ares?
• I'm trying to implement multiple dns requests and it would be really useful to have a way to recollect requests and responses unless there is already some mechanics in place that I'm not understanding from the documentation

As an exemple:

void ares_gethostbyname(ares_channel channel, const char *name,
int family, ares_host_callback callback, void *arg)

You can use a partial function for that: https://docs.python.org/3.8/library/functools.html#functools.partial
