CURLOPT_HSTSWRITEDATA - Man Page

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 4th 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) {
  curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

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

  curl_easy_perform(curl);
}

Availability

Added in 7.74.0
