As I understand it, NSPR only has only one error code right now (Bug 164715 #7) Ideally, NSPR would add support for a couple more error codes: > gethostbyname() has four error codes: > > #define HOST_NOT_FOUND 1 /* Authoritive Answer Host not found */ > #define TRY_AGAIN 2 /* Non-Authoritive Host not found, or > SERVERFAIL */ > #define NO_RECOVERY 3 /* Non recoverable errors, FORMERR, REFUSED, > NOTIMP */ > #define NO_DATA 4 /* Valid name, no data record of requested > type */ This might need platform specific attention. Right now, we can't do things like error saying that we could not contact the DNS server. This is a distinct problem from requesting a hostname that is not in DNS (for example, the root cause if often connectivity problems).

why version=other?
