my understanding (from my Richard Stevens book) is that gethostbyname will
return ipv4 mapped ipv6 addresses by setting h_addrtype in hostent to
AF_INET6. gethostbyname doesn't have a second argument; gethostbyname2
does. if you want all the addresses of a host and you want them to be ipv4
mapped to ipv6, then you use gethostbyname.
what exact info are you looking for, though? one of those two functions
should give you all you need.
