GETNETGRENT(3)						   BSD Library Functions Manual 					    GETNETGRENT(3)

NAME
getnetgrent, innetgr, setnetgrent, endnetgrent -- netgroup database operations LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <netdb.h> int getnetgrent(char **host, char **user, char **domain); int innetgr(const char *netgroup, const char *host, const char *user, const char *domain); void setnetgrent(const char *netgroup); void endnetgrent(void); DESCRIPTION
These functions operate on the netgroup database file /etc/netgroup which is described in netgroup(5). The database defines a set of net- groups, 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 (char *)0 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. The setnetgrent() function also sets the off- set 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 (char *)0 those fields will match any string value in the netgroup member. RETURN VALUES
The function 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. FILES
/etc/netgroup netgroup database file COMPATIBILITY
The netgroup members have three string fields to maintain compatibility with other vendor implementations, however it is not obvious what use the domain string has within BSD. SEE ALSO
netgroup(5) BUGS
The function getnetgrent() returns pointers to dynamically allocated data areas that are freed when the function endnetgrent() is called. BSD
