NAME

     CURLOPT_FTP_USE_EPSV - enable/disable use of EPSV

SYNOPSIS

     #include <curl/curl.h>

     CURLcode           curl_easy_setopt(CURL            *handle,
     CURLOPT_FTP_USE_EPSV, long epsv);

DESCRIPTION

     Pass epsv as a long. If the value is 1, it tells curl to use
     the  EPSV command when doing passive FTP downloads (which it
     does by default).  Using  EPSV  means  that  it  will  first
     attempt  to use EPSV before using PASV, but if you pass zero
     to this option, it will not try using EPSV, only plain PASV.

     If the server is an IPv6 host,  this  option  will  have  no
     effect as of 7.12.3.

DEFAULT

     1

PROTOCOLS

     FTP

EXAMPLE

     CURL *curl = curl_easy_init();
     if(curl) {
       curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/old-server/file.txt");

       /* let's shut off this modern feature */
       curl_easy_setopt(curl, CURLOPT_FTP_USE_EPSV, 0L);

       ret = curl_easy_perform(curl);

       curl_easy_cleanup(curl);
     }

AVAILABILITY

     Along with FTP

RETURN VALUE

     Returns    CURLE_OK    if    FTP    is    supported,     and
     CURLE_UNKNOWN_OPTION if not.
