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

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

       ret = curl_easy_perform(curl);
