.TH CURLOPT_MAXFILESIZE 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
|
|
|
.SH NAME
|
|
|
|
|
CURLOPT_MAXFILESIZE \- maximum file size allowed to download
|
|
|
|
|
.SH SYNOPSIS
|
|
|
|
|
#include <curl/curl.h>
|
|
|
|
|
|
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXFILESIZE, long size);
|
|
|
|
|
.SH DESCRIPTION
|
|
|
|
|
Pass a long as parameter. This allows you to specify the maximum \fIsize\fP
|
|
|
|
|
(in bytes) of a file to download. If the file requested is found larger than
|
|
|
|
|
this value, the transfer will not start and \fICURLE_FILESIZE_EXCEEDED\fP will
|
|
|
|
|
be returned.
|
|
|
|
|
|
|
|
|
|
The file size is not always known prior to download, and for such files this
|
|
|
|
|
option has no effect even if the file transfer ends up being larger than this
|
|
|
|
|
given limit. This concerns both FTP and HTTP transfers.
|
|
|
|
|
|
|
|
|
|
If you want a limit above 2GB, use \fICURLOPT_MAXFILESIZE_LARGE(3)\fP.
|
|
|
|
|
.SH DEFAULT
|
|
|
|
|
None
