# 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 that can be done over SOCKS
# EXAMPLE
~~~c
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);
}
}
