JFFS (2) - File locking

JFFS (2) - File locking

[David Mackay]

Hi,
 
We are beginning to develop a product using JFFS initially (possibly2 in
the future) and are using file locks in order to both write locally and
read remotely with a Java client front end. Currently on Ext2 our
program uses the system call lockf() which works well, however we read
with interest that JFFS does not support hard links and may have a
problem with this call!!? Any comments?
 
Thanks, David

File locking doesn't involve the underlying filesystem, I believe - at 
least not for non-networked file systems. File locking on JFFS and JFFS2 
should just work.

Hard links are a completely separate issue. JFFS doesn't support them. 
JFFS2 does.
