NAME
       CURLOPT_USE_SSL - request using SSL / TLS for the transfer

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_USE_SSL, long level);

DESCRIPTION
       Pass  a  long  using  one of the values from below, to make libcurl use
       your desired level of SSL for the transfer.

       These are all protocols that start out plain text and get "upgraded" to
       SSL using the STARTTLS command.

       This is for enabling SSL/TLS when you use FTP, SMTP, POP3, IMAP etc.

       CURLUSESSL_NONE
              do not attempt to use SSL.

       CURLUSESSL_TRY
              Try using SSL, proceed as normal otherwise. Note that server may
              close the connection if the negotiation does not succeed.

       CURLUSESSL_CONTROL
              Require  SSL  for  the   control   connection   or   fail   with
              CURLE_USE_SSL_FAILED.

       CURLUSESSL_ALL
              Require    SSL    for    all    communication   or   fail   with
              CURLE_USE_SSL_FAILED.

DEFAULT
       CURLUSESSL_NONE

PROTOCOLS
       FTP, SMTP, POP3, IMAP, LDAP

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/dir/file.ext");

         /* require use of SSL for this, or fail */
         curl_easy_setopt(curl, CURLOPT_USE_SSL, (long)CURLUSESSL_ALL);

         /* Perform the request */
         curl_easy_perform(curl);
       }
