Subject: hi-res mtime userspace interface
Date: Sun, 20 Jan 2008 21:09:52 +0800 [thread overview]
Message-ID: <47934820.7020209@metaparadigm.com> (raw)
Is there an existing linux userspace interface for accessing the
microsecond or nanosecond level (a|m|c)times of filesystems that support
them (e.g. ext4, xfs)? and possibly also the generation counters used by
NFS.
I notice sys_utimes is able to set microsecond (c|a|m)times but I can't
find an associated interface to read them (I've googled to no avail).
(also noticing freebsd and darwin's struct stat contains struct timespec
for these as well as an st_gen field - although I do realise how
incredibly difficult it would be to add these to linux's struct stat).
