+
+# 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);
+  }
+}
