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.

    /* a drftpd server, do it */
    curl_easy_setopt(curl, CURLOPT_FTP_USE_PRET, 1L);
