CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PROXY_ERROR, long *detail);

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.

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);
  }
}
