getnetgrent(machinep, userp, domainp) char **machinep, **userp, **domainp;
setnetgrent(netgroup) char *netgroup
endnetgrent()
innetgr(netgroup, machine, user, domain) char *netgroup, *machine, *user, *domain;
getnetgrent() returns the next member of a network group. After the call, machinep will contain a pointer to a string containing the name of the machine part of the network group member, and similarly for userp and domainp. If any of machinep, userp or domainp is returned as a NULL pointer, it signifies a wild card. getnetgrent() will use malloc.3v to allocate space for the name. This space is released when a endnetgrent() call is made. getnetgrent() returns 1 if it succeeded in obtaining another member of the network group, 0 if it has reached the end of the group.
getnetgrent() establishes the network group from which getnetgrent() will obtain members, and also restarts calls to getnetgrent() from the beginning of the list. If the previous setnetgrent() call was to a different network group, a endnetgrent() call is implied. endnetgrent() frees the space allocated during the getnetgrent() calls. innetgr returns 1 or 0, depending on whether netgroup contains the machine, user, domain triple as a member. Any of the three strings machine, user, or domain can be NULL, in which case it signifies a wild card.
The Network Information Service (NIS) must be running when using getnetgrent(), since it only inspects the NIS netgroup map, never the local files.
The Network Information Service (NIS) was formerly known as Sun Yellow Pages (YP). The functionality of the two remains the same; only the name has changed.
