NAME
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 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
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); } }
