NAME    [Toc]    [Back]

       res_init  -  Search for a default domain name and Internet

SYNOPSIS    [Toc]    [Back]

       #include <sys/types.h>  #include  <netinet/in.h>  #include
       <arpa/nameser.h> #include <resolv.h>

       void res_init(
               void );

LIBRARY    [Toc]    [Back]

       Standard C Library (libc)

DESCRIPTION    [Toc]    [Back]

       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    [Toc]    [Back]

       If   the   /etc/resolv.conf   file  does  not  exist,  the
       res_init() function attempts  name  resolution  using  the
       local /etc/hostsfile.  If the system 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    [Toc]    [Back]

       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
