Synopsis
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HSTSREADDATA, void *pointer);

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); } }
