Dear Friend,
Maybe de system method can help you.
Did you try  system(’shutdown.exe’);   ?

This method calls the shutdow app in windows system.The usage of this 
app is:

Usage: shutdown.exe [-i | -l | -s | -r | -a] [-f] [-m \\computername] 
[-t xx] [-
c "comment"] [-d up:xx:yy]

No args Display this message (same as -?)
-i Display GUI interface, must be the first option
-l Log off (cannot be used with -m option)
-s Shutdown the computer
-r Shutdown and restart the computer
-a Abort a system shutdown
-m \\computername Remote computer to shutdown/restart/abort
-t xx Set timeout for shutdown to xx seconds
-c “comment” Shutdown comment (maximum of 127 characters)
-f Forces running applications to close without war
ning
-d [u][p]:xx:yy The reason code for the shutdown
u is the user code
p is a planned shutdown code
xx is the major reason code (positive integer le
ss than 256)
yy is the minor reason code (positive integer le
ss than 65536)

If you are on a linux , you shold use the equivalent app to shutdown the 
system , maybe the init 0 for example.

Hope helped you.
