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

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
