res_init

res_init(3)						     Library Functions Manual						       res_init(3)

NAME

       res_init - Searches for a default domain name and Internet address

LIBRARY

       Standard C Library (libc.a, libc.so)

SYNOPSIS

       #include <sys/types.h> #include <netinet/in.h> #include <arpa/nameser.h> #include <resolv.h>
       void res_init ( void );

DESCRIPTION

       The  res_init()	function reads the /etc/resolv.conf file for the default domain name and the Internet address of the initial hosts running
       the name server, even if the name server is not functioning.

       The res_init() function is one of a set of subroutines that form the resolver, a set of functions that resolve domain names.  All  resolver
       functions  use  the  /usr/include/resolv.h  header file, which defines the _res data structure.	The res_init() function stores domain name
       information in the _res data structure.

NOTES

       If the /etc/resolv.conf file does not exist, the res_init() function attempts name resolution using the local /etc/hosts file.  If the sys-
       tem is not using a domain name server, the /etc/resolv.conf file should not exist.  The /etc/host file should be present on the system even
       if the system is using a name server.  In this instance, the file should contain the host IDs that the system requires to function even	if
       the name server is not functioning.

FILES

       Contains the name server and domain name.
	Contains hostnames and their addresses for hosts in a network.	This file is used to resolve a hostname into an Internet address.

RELATED INFORMATION
