D has an answer:

I still don't recommend doing this, for previously stated reasons.

Well, C's array symbol is used as a pointer to the first
element and D allows array indexing for pointers as well.
Here is the C code:
// c.c
#include "stdio.h"
int tab[64];
int *get() {
return tab;// or &tab[0]
}

extern(C) int tabLength(); // mythical mechanism or no?
@property int[] dtab { return tab.ptr[0 .. tabLength]; }
And I've used mythical syntax also! Should be:
@property int[] dtab() { return tab.ptr[0 .. tabLength]; }

I think this should work:

Then if you want to access the elements, use the tab.ptr[elem]
If it's a global variable, tack on __gshared.

My assumption is you do not know the size of the array.

Let suppose there is an array, somewhere in lib.c.
int tab[64];
and there is header file lib.h with following reference:
