NAME

CURLOPT_HSTSWRITEDATA - 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 get as input in the fourth argument to the callback.

This option does not enable HSTS, you need to use CURLOPT_HSTS_CTRL(3) to do that.

DEFAULT

NULL

PROTOCOLS

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_HSTSWRITEFUNCTION callback */
curl_easy_setopt(curl, CURLOPT_HSTSWRITEDATA, &this);

curl_easy_perform(curl);
}
}
