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.
