Close. ;)

For arrays, you are correct; it's (array*)->size

For maps, however, the size can be determined via (*):

    unsigned short nSize;

    /* Optimized division by 2 (using integer division, of course) */
    nSize = (array*)->size >> 1;

    /* This is the part that you are missing */
    if ( (array*)->hashed != NULL )
    {
        nSize += (array*)->hashed->size;
    }


(*) -- The above code was effectively copied from array.c->map_size().
