NAME
       CURLOPT_FTP_RESPONSE_TIMEOUT - time allowed to wait for FTP response

SYNOPSIS
       #include <curl/curl.h>

       CURLcode  curl_easy_setopt(CURL  *handle, CURLOPT_FTP_RESPONSE_TIMEOUT,
       long timeout);

DESCRIPTION
       Pass a long.  Causes libcurl to set a timeout period  (in  seconds)  on
       the  amount of time that the server is allowed to take in order to send
       a response message for a command before the session is considered dead.
       While  libcurl  is  waiting  for  a response, this value overrides CUR-
       LOPT_TIMEOUT(3). It is recommended that if  used  in  conjunction  with
       CURLOPT_TIMEOUT(3),  you set CURLOPT_FTP_RESPONSE_TIMEOUT(3) to a value
       smaller than CURLOPT_TIMEOUT(3).

DEFAULT
       None

PROTOCOLS
       FTP

EXAMPLE
       TODO

AVAILABILITY
       Added in 7.10.8

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