- make DEFAULT sections less repetitive - make historic mentions use HISTORY - generate the protocols section on `# %PROTOCOLS%` instead of guessing where to put it - generate the availability section on `# %AVAILABILITY%` instead of guessing where to put it - make the protocols section more verbose Closes #14227

# NAME
|
|
|
|
CURLOPT_FTP_USE_EPRT - use EPRT for FTP
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_USE_EPRT, long enabled);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Pass a long. If the value is 1, it tells curl to use the EPRT command when
|
|
doing active FTP downloads (which is enabled by
|
|
CURLOPT_FTPPORT(3)). Using EPRT means that libcurl first attempts to use
|
|
EPRT before using PORT, but if you pass zero to this option, it avoids using
|
|
EPRT, only plain PORT.
|
|
|
|
The EPRT command is a slightly newer addition to the FTP protocol than PORT
|
|
and is the preferred command to use since it enables IPv6 to be used. Old FTP
|
|
servers might not support it, which is why libcurl has a fallback mechanism.
|
|
Sometimes that fallback is not enough and then this option might come handy.
|
|
|
|
If the server is an IPv6 host, this option has no effect as EPRT is necessary
|
|
then.

# %PROTOCOLS%

# EXAMPLE

if(curl) {

|
CURLcode res;
|
|
curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/file.txt");
|
|
|
|
/* contact us back, aka "active" FTP */
|
|
curl_easy_setopt(curl, CURLOPT_FTPPORT, "-");
|
|
|
|
/* FTP the way the neanderthals did it */
|
|
curl_easy_setopt(curl, CURLOPT_FTP_USE_EPRT, 0L);
|
|
|
|
res = curl_easy_perform(curl);
|
