#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HAPROXY_CLIENT_IP,

When this parameter is set to a valid IPv4 or IPv6 numerical address,
the library sends this address as client address in the HAProxy PROXY

This option is an alternative to CURLOPT_HAPROXYPROTOCOL(3) as that one
cannot use a specified address.
