|
.SH NAME
|
||
|
|
CURLOPT_MAXFILESIZE \- maximum file size allowed to download
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXFILESIZE, long size);
|
||
|
|
.fi
|
||
|
|
.SH DESCRIPTION
|
||
|
|
Pass a long as parameter. This specifies the maximum accepted \fIsize\fP (in
|
||
|
|
bytes) of a file to download. If the file requested is found larger than this
|
||
|
|
value, the transfer is aborted and \fICURLE_FILESIZE_EXCEEDED\fP is returned.
|
||
|
|
Passing a zero \fIsize\fP disables this, and passing a negative \fIsize\fP yields a
|
||
|
|
\fICURLE_BAD_FUNCTION_ARGUMENT\fP.
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
If you want a limit above 2GB, use \fICURLOPT_MAXFILESIZE_LARGE(3)\fP.
|
||
|
|
|
||
|
|
Since 8.4.0, this option also stops ongoing transfers if they reach this
|
||
|
|
threshold.
|
||
|
|
.SH DEFAULT
|
||
|
|
0, meaning disabled.
|
||
|
|
