gethostbyaddr, et alia

["Victor J. Orlikowski" <v....@gte.net>]

So, gethostbyname is handled by gethostbyname_r, and the corresponding
ifdefs....

Do we also need to handle gethostbyaddr and getservbyname in the same
manner, for thread safety's sake?

Also, I may be missing some history, but is there a reason that apr
does not yet have an apr_gethostbyname function?

Set GETHOSTBYNAME_IS_THREAD_SAFE in the hints file.  -- justin

We do use getservbyname and I wondered about that today as well...  Also the
gethostbyname_r on beos is broken in the current version (segfaults) but
gethostbyname is thread safe so what's the best way of doing that - hints
file?

Argh. Addressing to the list, plus some changes....

Can do.

Yes, I see. However...
What if we simply want to do a gethostbyname, without all the rest of
the rigmarole required to fill in the sockaddr?

Or, suppose I want to hold onto the hostent produced by the
gethostbyname (which we do, in the proxy, when we are handling
directly connected hosts)? apr_sockaddr_info_get() either uses
getaddrinfo or gethostbyname, preferring getaddrinfo if it is
available.

Or is this considered broken behavior, and should we learn to use the
apr_sockaddr_t, and like it? :)

when there is such a routine

see apr_sockaddr_info_get()
