Pointer passed to the hsts read callback
Usage
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HSTSREADDATA, void *pointer);
Overview
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.
Examples
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);
}
}
