relan [Fri, 2 Oct 2009 16:40:45 +0000 (16:40 +0000)]
Add function that converts Unix time to exFAT time.
Unfortunately Earth rotation period is about 365 1/4 days, not 256
(for example). That is why this code is so complicated.
relan [Fri, 2 Oct 2009 16:15:31 +0000 (16:15 +0000)]
Add macro that checks whether year is leap.
Only XX and XXI centuries are considered, so the check is simplified.

Add parentheses to macro definition.
relan [Wed, 30 Sep 2009 08:57:33 +0000 (08:57 +0000)]

Fix atime and mtime for the root directory.
Set zero (i.e. 1 Jan 1970) atime and mtime for the root directory (as
Linux does) instead of senseless mount time.
relan [Mon, 28 Sep 2009 09:20:03 +0000 (09:20 +0000)]
Calculate root directory size and represent it.
relan [Mon, 28 Sep 2009 08:56:07 +0000 (08:56 +0000)]

Return error if entry type is unrecognized.
relan [Thu, 17 Sep 2009 19:16:25 +0000 (19:16 +0000)]

Add check of malloc() return value.
relan [Mon, 14 Sep 2009 18:44:13 +0000 (18:44 +0000)]
