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¶

This functionality affects ftp only

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);


    curl_easy_cleanup(curl);


  }
}
