IEnumFORMATETC::Next

  • 项目

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 the pceltFetched parameter unless the caller passed in NULL for that parameter.

HRESULT Next(
  ULONG celt,
  FORMATETC* 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. The caller can pass in NULL if celt is 1.

Return Values

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