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.

PROTOCOLS
This functionality affects all supported protocols

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);
  }
}

AVAILABILITY
Added in curl 7.73.0

RETURN VALUE
curl_easy_getinfo(3) returns a CURLcode indicating success or error. CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).
