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. FFIILLEESS /etc/netgroup netgroup database file SSEEEE AALLSSOO nneettggrroouupp(_5) 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. 4.4BSD June 4, 1993 1
