.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.
|
|
|
|
|
|
2021-07-23 14:56:52 +08:00
|
|
|
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.
|
2014-06-19 19:53:13 +08:00
|
|
|
|
|
|
|
|
If you want a limit above 2GB, use \fICURLOPT_MAXFILESIZE_LARGE(3)\fP.
|
|
|
|
|

|
|
|
None
