NAME¶
CURLOPT_DNS_LOCAL_IP4 - IPv4 address to bind DNS resolves to
SYNOPSIS¶
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DNS_LOCAL_IP4, char *address);
DESCRIPTION¶
Set the local IPv4
address that the resolver should bind to. The argument
should be of type char * and contain a single numerical IPv4 address as a
string. Set this option to NULL to use the default setting (don't bind to a
specific IP address).
DEFAULT¶
NULL
PROTOCOLS¶
All
EXAMPLE¶
TODO
AVAILABILITY¶
This option requires that libcurl was built with a resolver backend that
supports this operation. The c-ares backend is the only such one.
Added in 7.33.0
RETURN VALUE¶
Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not,
CURLE_NOT_BUILT_IN if support was disabled at compile-time, or
CURLE_BAD_FUNCTION_ARGUMENT when given a bad address.
