CURLOPT_HSTSREADDATA - pointer passed to the HSTS read callback
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HSTSREADDATA, void *pointer);
Data pointer to pass to the HSTS read function. If you use the CURLOPT_HSTSREADFUNCTION(3) option, this is the pointer you get as input in the 3rd argument to the callback.
This option does not enable HSTS, you need to use CURLOPT_HSTS_CTRL(3) to do that.

This feature is only used for HTTP(S) transfer.
