res_init() is not typically called directly by the application; rather it is
called by the first resolver function that is used.  Do "man resolver" for a
list of the functions that you can grep for in the source (or you can search
for "res_" and "dn_" since they all start with one of those).

Actually, those functions may not be called directly from the emacs source at
all.  Something like "gethostbyname() may be called, which indirectly calls
the resolver.
