NAME
       CURLOPT_FAILONERROR - request failure on HTTP response >= 400

SYNOPSIS
       #include <curl/curl.h>

       CURLcode   curl_easy_setopt(CURL   *handle,  CURLOPT_FAILONERROR,  long
       fail);

DESCRIPTION
       A long parameter set to 1 tells the library to fail the request if  the
       HTTP  code  returned is equal to or larger than 400. The default action
       would be to return the page normally, ignoring that code.

       This method is not fail-safe and there are occasions where non-success-
       ful response codes will slip through, especially when authentication is
       involved (response codes 401 and 407).

       You might get some amounts of headers transferred before this situation
       is  detected, like when a "100-continue" is received as a response to a
       POST/PUT and a 401 or 407 is received immediately afterwards.

       When this option is used and an error is detected, it  will  cause  the
       connection to get closed.

DEFAULT
       0, do not fail on error
