Changeset 2316 for trunk/src/emx/include/sys/stat.h

Timestamp:

Aug 29, 2005, 5:35:39 AM (20 years ago)

Message:

o Reworked the open backend, adding directory support. Some O_*

flags was changed in the process, breaking the old ABI.
This is not fully tested.

o Added more BSD fields to struct stat, breaking the old ABI.

The mtime field and ctime fields will now keep the same values
and the creation time is to be found in birthtime. This means that
ctime will be updated in a few places where it doesn't on unix - but
this is probably better than previously where it wasn't ever updated
when it should.
