CURLOPT_FTP_USE_PRET(3)    Library Functions Manual    CURLOPT_FTP_USE_PRET(3)

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
       transfers mode.

DEFAULT
       0

PROTOCOLS

EXAMPLE
       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           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);

           res = curl_easy_perform(curl);
