 Unfortunately FreeBSD does not support gethostbyname_r() at this time.
 However, it looks like bind9 has an implementation.

Hmm.  I knew I shoulda brought my Stevens book home.  I noticed in the
manpage that gethostbyname() requires the standard c lib (-lc), but
the process builds and links fine with the re-entrant c lib (-lc_r).

I'm pretty sure that doesn't fix the problem.  I looked at the
re-entrant details of gethostbyname_r() some time ago, but can't
remember the specifics since I haven't dealt with it for some time.

I'll look at the bind9 stuff.

Thanks.

thread safety and host lookups

2003-10-09 Thread Louis LeBlanc 
Hey folks.  I'm working on a port from Solaris to FreeBSD.  For the
most part, things are pretty straightforward, but I can't seem to find
the details on thread safety for some system calls.

gethostbyname_r() is the thread safe call that replaces
gethostbyname() on Solaris.

Is there a similar alternative call in FreeBSD, or was the default
system call modified to ensure thread safety?

TIA
