CURLOPT_FTP_USE_EPSV(3)    curl_easy_setopt options    CURLOPT_FTP_USE_EPSV(3)

NAME
       CURLOPT_FTP_USE_EPSV - enable/disable use of EPSV

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_USE_EPSV, long
       epsv);

DESCRIPTION
       Pass epsv as a long. If the value is 1, it tells curl to use the EPSV
       command when doing passive FTP downloads (which it does by default).
       Using EPSV means that it will first attempt to use EPSV before using
       PASV, but if you pass zero to this option, it will not try using EPSV,
       only plain PASV.

       If the server is an IPv6 host, this option will have no effect as of
       7.12.3.

DEFAULT
       1

PROTOCOLS
       FTP

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/old-server/file.txt");

         /* let's shut off this modern feature */
         curl_easy_setopt(curl, CURLOPT_FTP_USE_EPSV, 0L);

         ret = curl_easy_perform(curl);

         curl_easy_cleanup(curl);
       }

AVAILABILITY
       Along with FTP

RETURN VALUE
       Returns CURLE_OK if FTP is supported, and CURLE_UNKNOWN_OPTION if not.
