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 getnetgrent
() sets the three
pointer arguments to the strings of the next member of the current netgroup.
If any of the string pointers are NULL
that field is
considered a wildcard.
The functions setnetgrent
() and
endnetgrent
() set the current netgroup and terminate
the current netgroup respectively. If setnetgrent
()
is called with a different netgroup than the previous call, an implicit
endnetgrent
() is implied.
setnetgrent
() also sets the offset to the first
member of the netgroup.
The function innetgr
() searches for a
match of all fields within the specified group. If any of the
host, user, or domain
arguments are NULL
those fields will match any
string value in the netgroup member.
getnetgrent
() returns 0 for ``no more
netgroup members'' and 1 otherwise. The function
innetgr
() returns 1 for a successful match and 0
otherwise. The functions setnetgrent
() and
endnetgrent
() have no return value.
getnetgrent
() returns pointers to
dynamically allocated data areas that are free'd when the function
endnetgrent
() is called.
