reactos/posix/server/misc/init.c
Emanuele Aliberti bb24d01a48 PSX: early code for the PSXSS server program. Currently it is a W32 console application,
therefore it is not a proper subsystem, but it will be converted to native as soon as
it begins working. It probably does NOT work under ROS. I tested it under NT 4.0 SP 6a.
To see what it creates in the system name sapce, run WinObj, and HandleEx. If you
run csrterm.exe, it tries to connect to psxss.exe, but then dies because the API to
tell psxss to create a PSX process it not implemented yet. PSXDLL.DLL will connect
to \POSIX+\ApiPort (initial code in psx/lib/psxdll/misc/init.c is mute).
