No, it isn't.  buf is of type `char[SCREEN][COLS][MAX_SCREEN]', which (being
an array type) will decay into `char (*)[COLS][MAX_SCREEN]', i.e. pointer to
array of array of char.  If every object being passed through this parameter
has type `char (*)[COLS][MAX_SCREEN]', then you can declare the parameter to
have that type.  Otherwise, your best bet is to allocate `buf' at runtime
using dope vectors, so that it really does have type `char ***'.
