Question

I have a question regarding GetTickCount function,
I have two calls to this function in my code with several commands between them and the function in both calls returns same count.
i.e.

var1 = GetTickCount();
code
:
:
var2 = GetTickCount();

var1 and var2 has same values in it.

can someone help?

Answer 1

Assuming this is the Windows GetTickCount call, that’s entirely reasonable:

The resolution of the GetTickCount
function is limited to the resolution
of the system timer, which is
typically in the range of 10
milliseconds to 16 milliseconds.

Note that it’s only measuring milliseconds to start with – and you can do an awful lot in a millisecond these days.

The docs go on to say:

If you need a higher resolution timer,
use a multimedia timer or a
high-resolution timer.

Perhaps QueryPerformanceCounter would be more appropriate?
