Hi.

Is there a way to exit Photon and shutdown QNX 4 from C code.

We have a request for a system that will have no mouse, no keyboard and no
display.

The software needs to shutdown the system in response to an event.

Thanks

Augie

system(“shutdown”);

And this will exit Photon? Will there be any problems with open files from
pdm, etc…?

I’ve done it that way with no problems. To test simply open a pterm window and type shutdown.
Don’t use shutdown -f as it is fast and some files may not get closed (i.e. samba)

if you want to be certain…how about:

system (“slay photon”);
sleep(number_of_seconds_to_wait);
system (“shutdown”);

AFAIK this should be fine.
