power off pc with nextstep

Dear all
I was thinking that the power-off feature in Nextstep 3.3 always displays a message "its now safe to turn off the machine", then i need to power it off.
how hard do you think it will be to creat something to add to halt command so it can trigger low level ACPI shutdown?
i was thinking creating a halt script which would actually execute the real halt command then issue a acpi power off call, to shut down the pc.
Did anyone manage to achieve this.
im just thinking out loud
just saw this .c and .h in github

thanks and regards

Driverkit has inb(), inw(), inl(), outb(), outw() and outl().

Here is the pdf manual (https://www.nextcomputers.org/NeXTfiles/Software/OPENSTEP/Developer/DriverKit/DriverKit.pdf). Just search for those functions.

From the above link apparently shutdown now or halt are the commands used to shutdown NeXTSTEP.

Quote from: 09 System Startup and Shutdown - Shutting Down with a UNIX CommandThe shutdown command takes you to single-user mode. If you're using an Intel-based computer, the halt command prepares the computer so your can turn it off.

If you used the shutdown command, press the Power key and then type y when you're asked if you really want to turn off the computer. If you're using an Intel-based computer and you used the halt command, press the power switch on your computer when you see the message that it's safe to turn it off.
