NAME

       CURLOPT_HSTSREADDATA - pointer passed to the HSTS read callback

SYNOPSIS

       #include <curl/curl.h>

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

DESCRIPTION

       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.

DEFAULT

       NULL

PROTOCOLS

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

EXAMPLE

       struct MyData {
         void *custom;
       };

       int main(void)
       {
         CURL *curl = curl_easy_init();
         struct MyData this;
         if(curl) {
           curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

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

           curl_easy_perform(curl);
         }
       }
