Thus, the functionality is almost equal to inet_aton() (jus= t the way > the information is returned differs, but that's no functional change.) Follow-up: I've written a simple program to look up hosts using the OS-pr= ovided functions getaddrinfo() and inet_ntop(). If you (Sebastien) are intereste= d, take a look in /usr/src/domainlookup, although it's really boring. Output for "./getaddrinfo localhost 127.0.0.1 loopback": ### information for localhost ### addr 1: 127.0.0.1 (length 9) addr 2: 127.0.0.1 (length 9) addr 3: 127.0.0.1 (length 9) addr 4: 127.0.0.1 (length 9) addr 5: 127.0.0.1 (length 9) addr 6: 127.0.0.1 (length 9) ### information for 127.0.0.1 ### addr 1: 127.0.0.1 (length 9) addr 2: 127.0.0.1 (length 9) addr 3: 127.0.0.1 (length 9) ### information for loopback ### Thus, it doesn't look like a system issue. The returned addresses are jus= t fine. Even if something WERE to convert 127.0.0.1 to "localhost" and back to an= address, the address list for localhost is fine and does not contain the = unknown addresses. Seems like we're really seeing an nx bug on ppc64. I'll supply more information later when I get back.
