.SH DESCRIPTION
Pass a pointer to a long to receive a detailed error code when the most recent
transfer returned a \fBCURLE_PROXY\fP error. That error code matches the
\fBCURLproxycode\fP set.

The error code is zero (\fBCURLPX_OK\fP) if no response code was available.
.SH PROTOCOLS
This functionality affects all supported protocols
.SH EXAMPLE
.nf
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);
    }
