Hi,

a question about pointers as function parameters. Given that windows
can move code/data around in memory (I believe that is correct), is
it okay (or is it not okay) to pass pointers as the arguments to a
function? What I want to do is to have a function set the values of a
couple of variables (boring sort of stuff), but I am not sure that I
can pass the variables through pointers to the setting function. eg:

void CallerFunction ()
{
	int x, y;
	SetValue(&x, &y)
.
.
}

void SetValue(x, y)
int *x, *y;
{
	*x = 10;
	*y = 20;
}

thanks in advance,

kartik
