CURLOPT_DNS_INTERFACE(3)				     curl_easy_setopt options					  CURLOPT_DNS_INTERFACE(3)

NAME
       CURLOPT_DNS_INTERFACE - set interface to speak DNS over

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DNS_INTERFACE, char *ifname);

DESCRIPTION
       Pass a char * as parameter. Set the name of the network interface that the DNS resolver should bind to. This must be an interface name (not
       an address). Set this option to NULL to use the default setting (don't bind to a specific interface).

       The application does not have to keep the string around after setting this option.

DEFAULT
       NULL

EXAMPLE
       TODO

AVAILABILITY
       Added in 7.33.0. This option also requires that libcurl was built with a resolver backend that supports this operation. The c-ares  backend
       is the only such one.

RETURN VALUE
       Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or CURLE_NOT_BUILT_IN if support was disabled at compile-time.
