54 These functions operate on the netgroup database file which is described in
57 The database defines a set of netgroups, each made up of one or more triples:
58 .Bd -literal -offset indent
62 that defines a combination of host, user and domain.
63 Any of the three fields may be specified as ``wildcards'' that match any
68 sets the three pointer arguments to the strings of the next member of the
70 If any of the string pointers are
72 that field is considered a wildcard.
78 set the current netgroup and terminate the current netgroup respectively.
81 is called with a different netgroup than the previous call, an implicit
85 also sets the offset to the first member of the netgroup.
89 searches for a match of all fields within the specified group.
97 those fields will match any string value in the netgroup member.
101 returns 0 for ``no more netgroup members'' and 1 otherwise.
104 returns 1 for a successful match and 0 otherwise.
109 have no return value.
