> What I meant was: _distances is clearly a 1D array. Does the above C99 notation say "treat this 1D array like a 2D array of size [x][y]"? And then how it actually happens underneath is implementation dependent (e.g., whether it makes a silent/temporary array or pointers, or converts indexing)?

I don't think it can even be implementation dependent: here we just
define a pointer, and assign to it a casted value.
