# NAME
|
|
|
|
CURLOPT_FTP_USE_PRET - use PRET for FTP
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_USE_PRET, long enable);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Pass a long. If the value is 1, it tells curl to send a PRET command before
|
|
PASV (and EPSV). Certain FTP servers, mainly drftpd, require this non-standard
|
|
command for directory listings as well as up and downloads in PASV mode. Has
|
|
no effect when using the active FTP transfers mode.
