52 .Fn innetgr "const char *netgroup" "const char *host" "const char *user" "const char *domain"
54 .Fn setnetgrent "const char *netgroup"
58 These functions operate on the netgroup database file
63 The database defines a set of netgroups, each made up of one or more triples:
64 .Bd -literal -offset indent
67 that defines a combination of host, user and domain.
68 Any of the three fields may be specified as ``wildcards'' that match any
73 sets the three pointer arguments to the strings of the next member of the
75 If any of the string pointers are
77 that field is considered a wildcard.
83 set the current netgroup and terminate the current netgroup respectively.
86 is called with a different netgroup than the previous call, an implicit
92 also sets the offset to the first member of the netgroup.
96 searches for a match of all fields within the specified group.
104 those fields will match any string value in the netgroup member.
108 returns 0 for ``no more netgroup members'' and 1 otherwise.
111 returns 1 for a successful match and 0 otherwise.
116 have no return value.
