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 will 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¶

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);
}
