NAME

     CURLOPT_FTP_ALTERNATIVE_TO_USER - command to use instead  of
     USER with FTP

SYNOPSIS

     #include <curl/curl.h>

     CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_ALTERNATIVE_TO_USER,
                               char *cmd);

DESCRIPTION

     Pass a char * as parameter, pointing to a string which  will
     be  used  to  authenticate  if the usual FTP "USER user" and
     "PASS password" negotiation fails. This  is  currently  only
     known  to be required when connecting to Tumbleweed's Secure
     Transport FTPS server using client certificates for  authen-
     tication.

     The application does not have  to  keep  the  string  around
     after setting this option.

DEFAULT

     NULL

       ret = curl_easy_perform(curl);

       curl_easy_cleanup(curl);
     }
