quick timer question

[ftmthy412]

Hey all

I'm writing a simple app that will turn off my computer after a user-defined time has passed. How do I use a timer in C++ (with minutes or hours, not seconds)? Any links to helpful resources are appreciated also.
Thanks lot.

If you are using MFC, then use normal settimer,
if you are not using MFC
this code helps you

/* clock example: countdown */                           
#include <stdio.h>
#include <time.h>
#include <windows.h>

void wait ( int seconds )
{
	clock_t endwait;
	endwait = clock () + seconds * CLOCKS_PER_SEC ;
	while (clock() < endwait) {}
}

int main ()
{
	int n;
	printf ("Starting countdown...\n");
	for (n=3; n>0; n--)
	{
		printf ("%d\n",n);
		wait (1);
	}
	printf ("FIRE!!!\n");
	printf ("Shutting down system!!!\n");
/*
	1.EWX_LOGOFF: Logoff the current user.
	2. EWX_RESTART: Simply restart the computer.
	3. EWX_SHUTDOWN: Shut down but 'AT' style.
	4. EWX_POWEROFF: Shut down but 'ATX' style.                                              
*/

	ExitWindowsEx(EWX_POWEROFF,0);


	return 0;
}
