Hello list,

As far as I recall from K&R, isn't pointer arithmetic on a void
pointer banned? And any effort to do that results in an error -
because the compiler won't know by how much size to increment the
pointer for a statement like "ptr++"? But then how about this:

[rick@linux rick]$ cat t.c
#include <stdio.h>
int main()
{
    void *ptr = 0;
    printf("%d \n", ptr+1);
}
[rick@linux rick]$ gcc t.c
[rick@linux rick]$ ./a.out
1
[rick@linux rick]$

It compiles and runs fine ... !

TIA,

Rick
