At first time, I tried using gethostbyname, but it seems to support only AF_INET, and returns NULL when asked for a hostname that only resolves to an IPv6 address. Then I looked to getaddrinfo, but it seems to require a service name, that is inappropriate for simple name resolution… > 2. The code handles only AF_INET and AF_INET6 families.

If I can use getaddrinfo, I shall handle other families in a generic way. > 3. The code declares variables within a code block. Right, thank you, this is easy to fix. -- Tanguy Ortolo
