A program that shows padding issues and offsets
Hi,
When working in many client/server situations that data being passed is passed in data structures. It's important to know the padding arrangements between two architects, so here is an example program that shows how to see the offsets.
#include <stdio.h>
int main (void)
{
struct {
char a;
int i;
double d;
} st;
printf ("st size: %d\noffset a: %d\noffset i: %d\noffset d:%d\n",
sizeof (st),
((char *) (&st.a)) - ((char *)&st),
((char *) (&st.i)) - ((char *)&st),
((char *) (&st.d)) - ((char *)&st));
}
