How would i do this? i know i could use GetTickCount(), but it will just tell me how much time used, not how much time my process actually got during the time it ran. I''m looking for something like the time thingie that i use on unix, it tells it to me nicely

Try this function:

DWORD timeGetTime(VOID);
it requires winmm.h and winmm.lib

Basically it returns the amount of time that windows has been up and running...

so just do this:
long BeginTime = TimeGetTime();
long EndTime = 0;
long DeltaTime = 0;
// code and other crap

EndTime = TimeGetTime();
DeltaTime = EndTime - BeginTime;

oh yeah... it gives millisecond accuracy.

There are more precise functions you can use, but I haven''t had to use them yet.

I''m a fan of the HPT functions, such as QueryHighPerformanceTimer.

i''d do the same thing, but i''d call:

  //-----------------------------------------------------------------------------------------------------------------------------inline unsigned GetTime( void )// returns current tick count (in ms) using the hpt if it exists, otherwise it just calls GetTickCount{	static LARGE_INTEGER Frequency,Time;	static bool HighPerformanceTimerExists = (QueryPerformanceFrequency( &Frequency ) != 0);	if( HighPerformanceTimerExists )	{		QueryPerformanceCounter( &Time );		return unsigned( (1000u*Time.QuadPart)/Frequency.QuadPart );	}	else		return GetTickCount( );	}

if ur using MSVC
heh
