CURLOPT_FAILONERROR(3)					     curl_easy_setopt options					    CURLOPT_FAILONERROR(3)

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-successful 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

EXAMPLE

AVAILABILITY

RETURN VALUE
