.TH ARES_SET_SERVERS 3 "5 March 2010" |
|
.SH NAME |
|
ares_set_servers \- Initialize an ares_channel name servers configuration |
|
.SH SYNOPSIS |
|
.nf |
|
.B #include <ares.h> |
|
.PP |
|
.B int ares_set_servers(ares_channel \fIchannel\fP, struct ares_addr_node *\fIservers\fP) |
|
.fi |
|
.SH DESCRIPTION |
|
The \fBares_set_servers(3)\fP function initializes name servers configuration |
|
for the channel data identified by |
|
.IR channel , |
|
from a |
|
.IR 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 \fBares_get_servers(3)\fP 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. |
|
|
|
\fBares_set_servers(3)\fP does not take ownership of the linked list argument. |
|
The caller is responsible to free the linked list when no longer needed. |
|
|
|
This function is capable of handling IPv4 and IPv6 name server |
|
addresses simultaneously, rendering \fBares_init_options(3)\fP with |
|
optmask \fBARES_OPT_SERVERS\fP functionally obsolete except for |
|
IPv4-only name server usage. |
|
|
|
.SH RETURN VALUES |
|
.B ares_set_servers(3) |
|
may return any of the following values: |
|
.TP 15 |
|
.B ARES_SUCCESS |
|
The name servers configuration was successfuly initialized. |
|
.TP 15 |
|
.B ARES_ENOMEM |
|
The process's available memory was exhausted. |
|
.TP 15 |
|
.B ARES_ENODATA |
|
The channel data identified by |
|
.IR channel |
|
was invalid. |
|
.TP 15 |
|
.B ARES_ENOTINITIALIZED |
|
c-ares library initialization not yet performed. |

.SH AUTHOR |
|
Implementation of this function and associated library internals are based |
|
on code, comments and feedback provided 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. |
