CURLOPT_FAILONERROR(3) libcurl 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-success-
ful response codes 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 causes the con-
nection to get closed and CURLE_HTTP_RETURNED_ERROR is returned.
DEFAULT
0, do not fail on error
PROTOCOLS
HTTP
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
CURLcode ret;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
curl_easy_setopt(curl, CURLOPT_FAILONERROR, 1L);
ret = curl_easy_perform(curl);
if(ret == CURLE_HTTP_RETURNED_ERROR) {
/* an HTTP response error problem */
}
}
AVAILABILITY
Along with HTTP.
RETURN VALUE
Returns CURLE_OK if HTTP is enabled, and CURLE_UNKNOWN_OPTION if not.
