source: trunk/src/emx/include/unistd.h@ 2375

Last change on this file since 2375 was 2323, checked in by bird, 20 years ago

o Implemented fchdir().
o Implemented inheritance of open directory handles. Unfortunately,

I ran out of size bits for the bundle type, so the SPM bit is no
longer compatible with earlier versions. The consequences
of this are related to inheritance and signaling - so recompile!

3 * FreeBSD 5.3
4 *
5 * @changed Commented out stuff which isn't implemented, TCPIP stuff at bottom.
6 * @todo Several man-years.. ;) Serious, complete the FreeBSD 5.3 merge and
7 * implement all the functions. Currently there is a bunch of POSIX
8 * #defines missing.
