Retrieves the next celt items in the enumeration sequence. If there are fewer than the requested number of elements left in the sequence, it retrieves the remaining elements. The number of elements actually retrieved is returned through pceltFetched (unless the caller passed in NULL for that parameter).
HRESULT Next(
ULONG celt, //Number of elements requested
ELT_T[ ] rgelt, //Array of the elements
ULONG * pceltFetched //Pointer to the number of elements actually
// supplied
);
S_OK if the number of elements supplied is celt; S_FALSE otherwise.
