# NAME
|
||
|
|
|
||
|
|
CURLOPT_MAXFILESIZE_LARGE - maximum file size allowed to download
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXFILESIZE_LARGE,
|
||
|
|
curl_off_t size);
|
||
|
|
~~~
|
||
|
|
|
||
|
|
# DESCRIPTION
|
||
|
|
|
||
|
|
Pass a curl_off_t as parameter. This specifies the maximum accepted *size*
|
||
|
|
(in bytes) of a file to download. If the file requested is found larger than
|
||
|
|
this value, the transfer is aborted and *CURLE_FILESIZE_EXCEEDED* is
|
||
|
|
returned.
|
||
|
|
|
||
|
|
The file size is not always known prior to the download start, and for such
|
||
|
|
transfers this option has no effect - even if the file transfer eventually
|
||
|
|
ends up being larger than this given limit.
|
||
|
|
|
||
|
|
Since 8.4.0, this option also stops ongoing transfers if they reach this
|
||
|
|
threshold.
