Be aware (you probably are...) that there's NIS and NIS+.

FreeBSD supports NIS (though not NIS+) but doesn't have the
'yp_get_default_domain' man page you refer to.  I think the other BSDs and
most Linux distros are in the same boat.

Given the above, 'yp_get_default_domain' may be a NIS+ call, although
FreeBSD's nis (actually yp(4)) man page notes that many NIS functions
don't have man pages - the *BSDs & Linux using a freely distributable
implementation of NIS.

AFAIK, NIS+ is Solaris only, but its possible that SGI and HP may have
licensed it as well (I have access to no system of either of these latter
two to check).  I'm not aware of any freely available/distributable
implemention of NIS+.
