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¶

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