GC.sizeOf
size_t sizeOf( const scope void * p ) nothrow @nogcReturns the true size of the memory block referenced by p.

If p references memory not originally allocated by this garbage collector, points to the interior of a memory block, or if p is null, zero will be returned.
Parameters
p | A pointer to the root of a valid memory block or to null. |
Returns
The size in bytes of the memory block referenced by p or zero on error.
