     These functions operate on the netgroup database file _/_e_t_c_/_n_e_t_g_r_o_u_p which
     is described in netgroup(5).  The database defines a set of netgroups,
     each made up of one or more triples:

           (host, user, domain)
     that defines a combination of host, user and domain.  Any of the three
     fields may be specified as ``wildcards'' that match any string.

     The function ggeettnneettggrreenntt() sets the three pointer arguments to the
     strings of the next member of the current netgroup.  If any of the string
     pointers are ((cchhaarr **))00 that field is considered a wildcard.

     The functions sseettnneettggrreenntt() and eennddnneettggrreenntt() set the current netgroup
     and terminate the current netgroup respectively.  If sseettnneettggrreenntt() is
     called with a different netgroup than the previous call, an implicit
     eennddnneettggrreenntt() is implied.  SSeettnneettggrreenntt() also sets the offset to the
     first member of the netgroup.

     The function iinnnneettggrr() searches for a match of all fields within the
     specified group.  If any of the hhoosstt, uusseerr, or ddoommaaiinn arguments are ((cchhaarr
     **))00 those fields will match any string value in the netgroup member.

RREETTUURRNN VVAALLUUEESS
     The function ggeettnneettggrreenntt() returns 0 for ``no more netgroup members'' and
     1 otherwise.  The function iinnnneettggrr() returns 1 for a successful match and
     0 otherwise.  The functions sseettnneettggrreenntt() and eennddnneettggrreenntt() have no re-
     turn value.

CCOOMMPPAATTIIBBIILLIITTYY
     The netgroup members have three string fields to maintain compatibility
     with other vendor implementations, however it is not obvious what use the
     ddoommaaiinn string has within BSD.

BBUUGGSS
     The function ggeettnneettggrreenntt() returns pointers to dynamically allocated data
     areas that are free'd when the function eennddnneettggrreenntt() is called.
