shutdown function

[hughLg]

i'm using Windows XP, when i shut down the computer by access Start button, my computer will be shut down and turn off the whole power of my system.

i want to create a program to do this same thing, so in my function, i do this:

{
   system("shutdown -s -f");
   /* or system("shutdown -s -f -t 01") to shutdown after 1 second. */
}

this'll shutdown my computer, but the power is not turn off entirely, there's still a message wait for me to press the power button at my CPU. the message is something like "It's safe to turn off your computer now".

any idea?
