NAME
CURLOPT_FTP_USE_PRET - use PRET for FTP
SYNOPSIS
#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 trans-
fers mode.
DEFAULT
0
PROTOCOLS
FTP
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/old-server/file.txt");
/* a drftpd server, do it! */
curl_easy_setopt(curl, CURLOPT_FTP_USE_PRET, 1L);
ret = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
AVAILABILITY
Added in 7.20.0
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION
if not.
