Kurt has filed a new bug report against eglibc http://sourceware.org/bugzilla/show_bug.cgi?id=15726 which draws the developers' attention to RFC3493 which specifies the return values of getaddrinfo(). These should be as follows.Further discussion can best be carried on in the upstream Bugzilla ticket. -- Thomas Hood- Things work as expected: return 0 - The nameserver replies that the hostname does not exist: EAI_FAIL - The nameserver doesn't reply, or replies with a temporary failure: EAI_AGAIN - You used AI_NUMERICHOST or AI_NUMERICSERV and didn't give a number: EAI_NONAME |
