digitalmars.D.bugs - Documentation error - array structure definition

The http://www.digitalmars.com/d/abi.html page says:

A dynamic array consists of:
    0: pointer to array data
    4: array dimension

This is arse-about-face, surely? If it's correct, then I've got some
seriously helpful magic imps helping me out on code interfacing between C
and D

Yours, puzzled.

Would you care to elaborate? Stewart. -- My e-mail is valid but not my primary mailbox, aside from its being the unfortunate victim of intensive mail-bombing at the moment. Please keep replies on the 'group where everyone may benefit.

Well, the Open-RJ header defines a string as:

struct ORJStringA
{
    size_t      len;        /*!< The number of characters in the string
*/
    char const  *ptr;       /*!< Pointer to the first element in the string
*/
};

The lib links and runs with D, treating the ORJStringA as char[],
seamlessly.

Of course, a simpler way of looking at it is that fmt specifiers for D strings
are %.*s. In C, one would write the args as printf("%.*s\n", len, ptr);

The doc is wrong. I'll fix it.
