Brad House 973023b4b9 ares_status_t enum for status codes (#567 ) The list of possible error codes in c-ares was a #define list. This not only doesn't provide for any sort of type safety but it also lacks clarification on what a function may return or what it takes, as an int could be an ares status, a boolean, or possibly even a length in the current code. We are not changing any public APIs as though the C standard states the underlying size and type of an enum is int, there are compiler attributes to override this as well as compiler flags like -fshort-enums. GCC in particular is known to expand an enum's width based on the data values (e.g., it can emit a 64bit integer enum). All internal usages should be changed by this PR, but of course, there may be some I missed. Fix By: Brad House (@bradh352)		1 year ago
