Comment (by nbruin):
OK, my C skills are insufficient for this:
{{{
#include<stdio.h>
typedef struct{
int a; int b; int c; int d; int e;
} composite;
typedef composite *pointer;
void main() {
pointer v;
printf("sizeof(composite)=%d\n",sizeof(composite));
printf("sizeof(t)=%d\n",sizeof(t));
printf("sizeof(*v)=%d\n",sizeof(*v));
};
}}}
produces the desired output:
{{{
sizeof(composite)=20
sizeof(pointer)=8
sizeof(*v)=20
}}}
So if I have my hands on an instance of a "pointer" variable, I can get
the size of the structure pointed to by dereferencing. However, if I want
to get this straight from the pointer type there doesn't seem to be a
syntax for it. `sizeof(*pointer)` gives an error ... How do you get that
information?
