NAME
       CURLOPT_SSL_VERIFYSTATUS - verify the certificate's status

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_VERIFYSTATUS, long verify);

DESCRIPTION
       Pass a long as parameter set to 1 to enable or 0 to disable.

       This  option  determines  whether  libcurl  verifies  the status of the
       server cert using the "Certificate Status Request" TLS extension  (aka.
       OCSP stapling).

       Note that if this option is enabled but the server does not support the
       TLS extension, the verification will fail.

DEFAULT
       0

PROTOCOLS
       All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
         /* ask for OCSP stapling! */
         curl_easy_setopt(curl, CURLOPT_SSL_VERIFYSTATUS, 1L);
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }

AVAILABILITY
       Added in 7.41.0.  This  option  is  currently  only  supported  by  the
       OpenSSL, GnuTLS and NSS TLS backends.

RETURN VALUE
       Returns CURLE_OK if OCSP stapling is supported by the SSL backend, oth-
       erwise returns CURLE_NOT_BUILT_IN.
