NAME
       CURLOPT_FTP_USE_PRET - enable the PRET command

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
       transfers 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
