CURLINFO_SSL_VERIFYRESULT(3)                          Library Functions Manual

NAME
       CURLINFO_SSL_VERIFYRESULT - get the result of the certificate
       verification

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SSL_VERIFYRESULT,
                                  long *result);

DESCRIPTION
       Pass a pointer to a long to receive the result of the server SSL
       certificate verification that was requested (using the
       CURLOPT_SSL_VERIFYPEER(3) option).

       0 is a positive result. Non-zero is an error.

PROTOCOLS
       This functionality affects all TLS based protocols: HTTPS, FTPS, IMAPS,
       POP3S, SMTPS etc.

       This option works only with the following TLS backends: GnuTLS and
       OpenSSL

EXAMPLE
       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           long verifyresult;

           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

           res = curl_easy_perform(curl);
           if(res) {
             printf("error: %s\n", curl_easy_strerror(res));
             curl_easy_cleanup(curl);
             return 1;
           }

           res = curl_easy_getinfo(curl, CURLINFO_SSL_VERIFYRESULT,
                                   &verifyresult);
           if(!res) {
             printf("The peer verification said %s\n",
                    (verifyresult ? "bad" : "fine"));
           }
           curl_easy_cleanup(curl);
         }
       }

AVAILABILITY

RETURN VALUE
       Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION
