Subject: how to pass params to inline functions by reference or value?
Date: Thu, 10 Apr 2008 05:55:00 -0000	[thread overview]
Message-ID: <1207801566.12695.8.camel@vm-laptop> (raw)

Hello,

I'm trying to decide on the best way to pass parameters to inline
function. For example, the two functions below:

inline int
sum(atype_t *x)
{
  return x->a + x->b;
}

and

inline int
sum(atype_t x)
{
  return x.a + x.b;
}

Since the function is inline, my guess is that the compiler will
generate identical code for both. So there should be no performance
difference.

Is this assumption correct?
