Re: Halting a CPU

["Jeff Creem" <jeff@thecreems.com>]

I you really mean you want to issue the halt command then you need assembler
(or call an existing Ada or C wrapper that calls the assembler code).
However, I suspect
(WARNING STRONG SPECULATION FOLLOWS NOT BASED ON ANYTHING BUT
HUNCH)
that if you are on a normal OS that the halt instruction may be privileged
and not
allowed by normal userspace processes (i.e. I am speculating that this will
not be
allowed on Linux or Win NT).. If you are on a bare machine or small
real-time kernel
then this might work.
