C-binding external array.

[ciechowoj via Digitalmars-d-learn]

Is there a way to access a static array from D without knowing 
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:

extern int tab[];

How to declare `tab` in the D code without knowing the size of 
the array? In other words, how to map external declaration of the 
`tab` to the D code?
