IEnumXXXX::Next

  • Статья

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,
  ELT_T[] rgelt,
  ULONG * pceltFetched
);

Parameters

  • celt
    [in] Number of elements being requested.
  • rgelt
    [out] Array of size celt (or larger) of the elements of interest. The type of this parameter depends on the item being enumerated.
  • pceltFetched
    [in, out] Pointer to the number of elements actually supplied in rgelt. Caller can pass in NULL if celt is one.

Return Value

S_OK if the number of elements supplied is celt; S_FALSE otherwise.
