/* gcc -mwindows -mno-cygwin -o halt.exe halt.c
NAME
halt - stopping the system
SYNOPSIS
halt [-pq]
DESCRIPTION
The halt utility logs off the current user, flushes the file system
buffers to disk, stops all processes (non-responsive processes are
only forced to stop in Windows 2000), and shuts the system down.
The options are as follows
-p Attempt to powerdown the system. If the powerdown fails, or
the system does not support software powerdown, the system
will halt.
-q Do not give processes a chance to shut down before halting or
restarting. This option should not normally be used.
