+ .TH ARES_SET_SERVERS_CSV 3 "30 June 2010"
+ .SH NAME
+ ares_set_servers_csv, ares_set_servers_ports_csv \- Set list of DNS servers to be used.
+ .SH SYNOPSIS
+ .nf
+ .B #include <ares.h>
+ .PP
++.B void ares_set_servers_csv(ares_channel \fIchannel\fP, const char* \fIservers\fP)
++.fi
++.SH DESCRIPTION
++The \fBares_set_servers_csv\fP function sets the list of DNS servers
++that ARES will query. The format of the servers option is:
+ .B int ares_set_servers_csv(ares_channel \fIchannel\fP, const char* \fIservers\fP)
+ .B int ares_set_servers_ports_csv(ares_channel \fIchannel\fP, const char* \fIservers\fP)
+ .fi
+ .SH DESCRIPTION
+ The \fBares_set_servers_csv\fP and \fBares_set_servers_ports_csv\fPfunctions set
+ the list of DNS servers that ARES will query. The format of the servers option is:
+
+ host[:port][,host[:port]]...
+
+ For example:
+
+ 192.168.1.100,192.168.1.101,3.4.5.6
++
++.SH SEE ALSO
++.BR ares_set_servers (3)
++.SH NOTES
++The port option is currently ignored by c-ares internals
++and the standard port is always used.
++
++This function was added in c-ares 1.7.2
+ .PP
+ The \fBares_set_servers_csv\fP function will ignore any port values specified in
+ the input string, whereare the \fBares_set_servers_ports_csv\fP function will
+ apply any specified port values as the UDP and TCP port to be used for that
+ particular nameserver.
+
+ .SH RETURN VALUES
+ .B ares_set_servers_csv(3)
+ This function may return any of the following values:
+ .TP 15
+ .B ARES_SUCCESS
+ The name servers configuration was successfully 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.
+ .TP 15
+ .B ARES_ENOTIMP
+ Changing name servers configuration while queries are outstanding is not implemented.
+ .SH SEE ALSO
+ .BR ares_set_servers (3)
+ .SH AVAILABILITY
+ \fBares_set_servers_csv\fP was added in c-ares 1.7.2;
+ \fBares_set_servers_ports_csv\fP was added in c-ares 1.11.0.
