I'd guess you want to be looking at adns.h, specifically the typedef'd
enum adns_status (ll. 205--255 in the copy I'm looking at), although
I've not looked at how the Python bindings to adns work. If you're
not familiar with enums, what you need to know is that it's just a
list of symbols defined to be integer values starting with 0 (eg
adns_s_ok is 0) and incrementing by one for each new symbol unless a
symbol is given an explicit value (adns_s_max_* in this case, used to
block out different types of error) -- in which case subsequent
symbols start incrementing from this value (so, eg, adns_s_timeout is
30).
