The gethostbyname4_r family of functions could return an empty list with
NSS_STATUS_SUCCESS.  The point I was trying to make is that the types do
not rule this out.

The other NSS service functions do not receive a pointer-to-pointer
argument (unlike the external glibc NSS functions), so the case that
pointer == NULL and NSS_STATUS_SUCCESS cannot happen.

Does this answer your question?

Thanks,
