timing in c++

Hi all,

Was just wondering the best method to keep track of time elapsed or just real time for that matter. I know that in glX code, you get use the function getMilliSeconds() to return time elapsed in milli seconds while in SDL you can use SDL_GetTicks() to do the same thing. However, is there a way of doing it in console mode?

I've tried reading some stuff on time/date in c++ but can't seem to figure it out (ie localtime/gmtime require a time argument). Any help/suggestions?

Thanks

If I get what you want: gettimeofday() returns a very fine grained time.
It's in time.h

Code:

#include <stdio.h>
#include <time.h>

int main(int argc, char **argv)
{
	clock_t startTime=0;

	while(1)
	{
		startTime=clock();
		while((clock()-startTime)/CLOCKS_PER_SEC<1000); //Sleep one second
		printf("One second elapsed!");
	}    
}

Now I don't know if thats perfect, because its off the top of my head. But I do know you need to look into clock() from time.h

Enjoy!
