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

    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);
  }
