gethostbyname_r()/gethostbyaddr_r() are not documented for a reason;
they are non-standard. There are at least 3 flavors out there last
time I checked, and portable code should not be using them. I
implemented them in NetBSD just to use them inside
getaddrinfo()/getnameinfo(). I chose not to hide them completely
and that was probably a bad decision seeing that some auto-configuration
schemes look for functions in libc and then try to use the functions
(even when they are no headers describing the functions; I'd really
like to know how do they deduce the arguments...) Why doesn't wine
use those instead (getaddrinfo()/getnameinfo())?
