DESCRIPTION

       Pass a pointer to a long to receive a detailed error code when the most
       recent transfer returned a CURLE_PROXY error. That error code matches
       the CURLproxycode set.

       The error code is zero (CURLPX_OK) if no response code was available.


PROTOCOLS

       All


EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

           curl_easy_setopt(curl, CURLOPT_PROXY, "socks5://127.0.0.1");
           res = curl_easy_perform(curl);
           if(res == CURLE_PROXY) {
             long proxycode;
             res = curl_easy_getinfo(curl, CURLINFO_PROXY_ERROR, &proxycode);
             if(!res && proxycode)
               printf("The detailed proxy error: %ld\n", proxycode);
           }
           curl_easy_cleanup(curl);
         }
       }
