20 ares_set_servers_csv, ares_set_servers_ports_csv \- Set list of DNS servers to be used.
26 int ares_set_servers_csv(ares_channel \fIchannel\fP, const char* \fIservers\fP)
28 int ares_set_servers_ports_csv(ares_channel \fIchannel\fP, const char* \fIservers\fP)
31 The \fBares_set_servers_csv\fP and \fBares_set_servers_ports_csv\fPfunctions set
32 the list of DNS servers that ARES will query. The format of the servers option is:
34 host[:port][,host[:port]]...

41 .BR ares_set_servers (3)
43 The port option is currently ignored by c-ares internals
44 and the standard port is always used.
46 This function was added in c-ares 1.7.2
48 The \fBares_set_servers_csv\fP function will ignore any port values specified in
49 the input string, whereare the \fBares_set_servers_ports_csv\fP function will
50 apply any specified port values as the UDP and TCP port to be used for that
51 particular nameserver.

69 c-ares library initialization not yet performed.
72 Changing name servers configuration while queries are outstanding is not implemented.
