NAME

       CURLOPT_HSTSWRITEDATA - pointer passed to the HSTS write callback

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HSTSWRITEDATA, void *pointer);

DESCRIPTION

       Data    pointer    to    pass   to   the   HSTS   write   function.   If   you   use   the
       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.

DEFAULT

       NULL

PROTOCOLS

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

EXAMPLE

       CURL *curl = curl_easy_init();
       struct MyData this;
       if(curl) {

         /* pass pointer that gets passed in to the
            CURLOPT_HSTSWRITEFUNCTION callback */
         curl_easy_setopt(curl, CURLOPT_HSTSWRITEDATA, &this);

         curl_easy_perform(curl);
       }
