Majorally Off topic but here is the windows shutdown/reboot code.?? I pulled it out of my code.


void
command(int cmd)
{
?????????????? char byte[1];
?????????????? 
?????????????? switch(cmd)
?????????????? {
?????????????? ?????????????? case 's':
?????????????? ?????????????? ???????????????? write(fd,"\nSHUTDOWN: Sure? (Y/N):", 23);
?????????????? ?????????????? ???????????????? read(fd, byte, 1);
?????????????? ?????????????? ???????????????? if((byte[0] == 'y') || (byte[0] == 'Y'))
?????????????? ?????????????? ???????????????? ???????????? shutdown(EWX_SHUTDOWN);
?????????????? ?????????????? ???????????????? break;
?????????????? ?????????????? case 'r':
?????????????? ?????????????? ???????????????? write(fd,"\nREBOOT: Sure? (Y/N):", 21);
?????????????? ?????????????? ???????????????? read(fd, byte, 1);
?????????????? ?????????????? ???????????????? if((byte[0] == 'y') || (byte[0] == 'Y'))
?????????????? ?????????????? ???????????????? ???????????? shutdown(EWX_REBOOT);
?????????????? ?????????????? ???????????????? break;
?????????????? ?????????????? case 'k':
?????????????? ?????????????? ?????????????? kill(cPid, SIGKILL);
?????????????? ?????????????? ?????????????? break;
?????????????? ?????????????? default:
?????????????? ?????????????? ?????????????? write(fd, "\n------------------------\n", 26);
?????????????? ?????????????? ?????????????? write(fd, "Commands:\n", 10);
?????????????? ?????????????? ?????????????? write(fd, "s:?????????? Shutdown\n", 17);
?????????????? ?????????????? ?????????????? write(fd, "r:?????????? Reboot", 14);
?????????????? ?????????????? ?????????????? write(fd, "k:?????????? kill Command\n", 21);
?????????????? ?????????????? ?????????????? write(fd, "\n------------------------\n", 26);
?????????????? ?????????????? ?????????????? break;
?????????????? }
?????????????? write(fd,'\n', 1);


?????????????? CMD=0;
}
