.TH CURLOPT_FTP_USE_EPSV 3 "November 04, 2020" "libcurl 7.77.0" "curl_easy_setopt options"

.SH NAME
CURLOPT_FTP_USE_EPSV \- enable/disable use of EPSV
.SH SYNOPSIS
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_USE_EPSV, long epsv);
.SH DESCRIPTION
Pass \fIepsv\fP 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.
.SH DEFAULT
1
.SH PROTOCOLS
FTP
.SH EXAMPLE
.nf
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);
}
.fi
.SH AVAILABILITY
Along with FTP
.SH RETURN VALUE
