NAME
       CURLOPT_FTPSSLAUTH - order in which to attempt TLS vs SSL

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTPSSLAUTH, long order);

DESCRIPTION
       Pass  a  long  using one of the values from below, to alter how libcurl
       issues "AUTH TLS" or "AUTH SSL" when FTP over SSL is activated. This is
       only interesting if CURLOPT_USE_SSL(3) is also set.

       Possible order values:

       CURLFTPAUTH_DEFAULT
              Allow libcurl to decide.

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

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

DEFAULT
       CURLFTPAUTH_DEFAULT

PROTOCOLS
       FTP

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/file.txt");
         curl_easy_setopt(curl, CURLOPT_USE_SSL, CURLUSESSL_TRY);
         /* funny server, ask for SSL before TLS */
         curl_easy_setopt(curl, CURLOPT_FTPSSLAUTH, (long)CURLFTPAUTH_SSL);
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }
