NAME

6       CURLOPT_MAXFILESIZE - maximum file size allowed to download
7

SYNOPSIS

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

DESCRIPTION

15       Pass a long as parameter. This allows you to specify the  maximum  size
16       (in bytes) of a file to download. If the file requested is found larger
17       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.
24
25       If you want a limit above 2GB, use CURLOPT_MAXFILESIZE_LARGE(3).
