SYNOPSIS

DESCRIPTION
       Pass  a  long  using one of the values from below, to alter how libcurl

              Allow libcurl to decide.

       CURLFTPAUTH_SSL
              Try "AUTH SSL" first, and only if that fails try "AUTH TLS".

              Try "AUTH TLS" first, and only if that fails try "AUTH SSL".

DEFAULT
       CURLFTPAUTH_DEFAULT

         curl_easy_setopt(curl, CURLOPT_USE_SSL, CURLUSESSL_TRY);
         /* funny server, ask for SSL before TLS */
         curl_easy_setopt(curl, CURLOPT_FTPSSLAUTH, CURLFTPAUTH_SSL);
         ret = curl_easy_perform(curl);
