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

Timestamp:

Author:

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.

-   As stated in the FreeBSD part, there is supposidly a limited number of bits
-   available. We'll try keep it suitable for 16bit just in case (don't care to
-   check what we use right now) because that'll enable us to share a 32-bit flag
-   variable per handle to both status (O_*) flags and descriptor (FD_*) flags.
-
-   When we've disabled a few BSD flags and leave out KERNEL stuff the following
-   bits are available:
-        0x0010, 0x0020, 0x0040, 0x0100, 0x1000, 0x4000*, 0x2000
