ares_set_servers

ARES_SET_SERVERS(3)					     Library Functions Manual					       ARES_SET_SERVERS(3)

NAME

       ares_set_servers - Initialize an ares_channel name servers configuration

SYNOPSIS

       #include <ares.h>

       int ares_set_servers(ares_channel channel, struct ares_addr_node *servers)

DESCRIPTION

       The  ares_set_servers(3) function initializes name servers configuration for the channel data identified by channel, from a servers pointer
       to a linked list of ares_addr_node structs holding name servers address data.

       The name server linked list pointer argument may be the result of a previous call to ares_get_servers(3) or a linked list of ares_addr_node
       structs setup by other means.

       This function replaces any potentially previously configured name servers with the ones given in the linked list. So, in order to configure
       a channel with more than one name server all the desired ones must be specified in a single list.

       ares_set_servers(3) does not take ownership of the linked list argument.  The caller is responsible for freeing the  linked  list  when	no
       longer needed.

       This  function  is  capable  of	handling  IPv4	and IPv6 name server addresses simultaneously, rendering ares_init_options(3) with optmask
       ARES_OPT_SERVERS functionally obsolete except for IPv4-only name server usage.

RETURN VALUES

       ares_set_servers(3) may return any of the following values:

       ARES_SUCCESS   The name servers configuration was successfuly initialized.

       ARES_ENOMEM    The process's available memory was exhausted.

       ARES_ENODATA   The channel data identified by channel was invalid.

       ARES_ENOTINITIALIZED
		      c-ares library initialization not yet performed.
