NAME

       CURLOPT_FTP_USE_EPRT - use EPRT for FTP

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_USE_EPRT, long enabled);

DESCRIPTION

       Pass  a  long.  If the value is 1, it tells curl to use the EPRT command when doing active
       FTP downloads (which is enabled by CURLOPT_FTPPORT(3)).  Using  EPRT  means  that  libcurl
       first  attempts  to  use  EPRT  before using PORT, but if you pass zero to this option, it
       avoids using EPRT, only plain PORT.

       The EPRT command is a slightly newer addition to the FTP protocol than  PORT  and  is  the
       preferred  command  to  use  since  it  enables IPv6 to be used. Old FTP servers might not
       support it, which is why libcurl has a fallback mechanism.  Sometimes that fallback is not
       enough and then this option might come handy.

       If the server is an IPv6 host, this option has no effect as EPRT is necessary then.

EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/file.txt");

           /* contact us back, aka "active" FTP */
           curl_easy_setopt(curl, CURLOPT_FTPPORT, "-");

           /* FTP the way the neanderthals did it */
           curl_easy_setopt(curl, CURLOPT_FTP_USE_EPRT, 0L);

           res = curl_easy_perform(curl);

           curl_easy_cleanup(curl);
         }
       }
