CURLOPT_HSTSREADDATA(3)

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'll get as input in the 3rd argument to the callback. This option doesn't 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) {
  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);
}

AVAILABILITY
