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

/* pass pointer that gets passed in to the
