       ares_set_servers    -   Initialize   an   ares_channel   name   servers


       #include <ares.h>

       int ares_set_servers(ares_channel channel, struct ares_addr_node *servers)


       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

       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


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

       ARES_SUCCESS   The   name   servers   configuration   was   successfuly

       ARES_ENOMEM    The process’s available memory was exhausted.

       ARES_ENODATA   The channel data identified by channel was invalid.

                      c-ares library initialization not yet performed.


       ares_get_servers(3), ares_init_options(3), ares_dup(3)


       ares_set_servers(3) was added in c-ares 1.7.1


       Implementation of this function and associated  library  internals  are
       based  on code, comments and feedback provided in November and December
       of 2008 by Daniel Stenberg, Gregor Jasny, Phil Blundell and  Yang  Tse,
       December  2009  by Cedric Bail, February 2010 by Jakub Hrozek. On March
       2010 Yang Tse shuffled all the bits and this function popped out.
