CURLOPT_FTP_USE_PRET(3)

CURLOPT_FTP_USE_PRET3

Use pret for ftp

Usage

#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_USE_PRET, long enable);

Overview

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.

    /* a drftpd server, do it */
    curl_easy_setopt(curl, CURLOPT_FTP_USE_PRET, 1L);
    result = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}
