Thread: Union of a struct

This should do it.

Code:

#include <stdio.h>

typedef union
{
   struct foo {
      int Field1;
      int Field2;
      int Field3;
      int Field4;
   } Sar;
   int Par[sizeof(struct foo)/sizeof(int)];
} Par_t;

int main()
{
    Par_t   p;
    printf("%zd\n", sizeof(p));
    printf("%zd\n", sizeof(p.Sar));
    printf("%zd\n", sizeof(p.Par));
    return 0;
}
