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.
