Subject: Improved Swaping Method In sort.c
Date: Wed, 30 Apr 2008 23:39:09 +0530 (IST)	[thread overview]
Message-ID: <191572.86791.qm@web94110.mail.in2.yahoo.com> (raw)

Thanks Jan,
Actually it should be
static void u32_swap(void *a, void *b)
{
    *(u32 *)b ^= *(u32 *)a;
    *(u32 *)a ^= *(u32 *)b;
    *(u32 *)b ^= *(u32 *)a;
}
But this code saves memory equaling two integers. What about that ?
