.TH CURLOPT_FTP_USE_EPSV 3 "November 26, 2021" "libcurl 7.83.1" "curl_easy_setopt options"
|
|
|
|
.SH NAME
|
|
CURLOPT_FTP_USE_EPSV \- use EPSV for FTP
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_USE_EPSV, long epsv);
|
|
.fi
|
|
.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
