NAME

6       CURLOPT_MAXFILESIZE_LARGE - maximum file size allowed to download
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXFILESIZE_LARGE,
12                                 curl_off_t size);
13

DESCRIPTION

15       Pass  a curl_off_t as parameter. This allows you to specify the maximum
16       size (in bytes) of a file to download. If the file requested  is  found
17       larger  than  this  value,  the transfer will not start and CURLE_FILE‐
18       SIZE_EXCEEDED will be returned.
19
20       The file size is not always known prior to download, and for such files
21       this  option  has  no  effect  even  if the file transfer ends up being
22       larger than this given limit. This concerns both FTP  and  HTTP  trans‐
23       fers.
