- .SH NAME

- .SH SYNOPSIS
- #include <curl/curl.h>
- CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DNS_INTERFACE, char *ifname);
- .SH 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).

- .SH EXAMPLE
- TODO
- .SH 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.
- .SH 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.
