#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HSTSWRITEDATA, void *pointer);

CURLOPT_HSTSWRITEFUNCTION(3) option, this is the pointer you will get as
input in the fourth argument to the callback.
This option does not enable HSTS, you need to use CURLOPT_HSTS_CTRL(3)
to do that.
