I am trying to set something up in a program that will shutdown or reboot linux after a specific command is received. The program is in C. Any ideas?

Is there a way to run command line commands from within a program?

use a system() call... or exec() i think.... you will of course need existing permissions to do that though.

Thanks!
It was the system() call...
So to shutdown I can call
system("shutdown -h now"); //or something similiar
and to reboot
system("reboot");//or something similiar
