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 authentication.

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

DEFAULT

       NULL

PROTOCOLS

       FTP

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/foo.bin");

         curl_easy_setopt(curl, CURLOPT_FTP_ALTERNATIVE_TO_USER, "two users");

         ret = curl_easy_perform(curl);

         curl_easy_cleanup(curl);
       }

AVAILABILITY

       Added in 7.15.5

RETURN VALUE

       Returns  CURLE_OK  if  the  option  is  supported,   CURLE_UNKNOWN_OPTION   if   not,   or
       CURLE_OUT_OF_MEMORY if there was insufficient heap space.
