Retrieves a specified number of items in the enumeration sequence.

Syntax

HRESULT Next(
  [in]  ULONG         celt,
  [out] IProgressItem **rgelt,
  [out] ULONG         *pceltFetched
);

Parameters

[in] celt

Number of items to retrieve.

[out] rgelt

Array of IProgressItem interfaces. You must release each interface in rgelt when done.

[out] pceltFetched

Number of elements returned in rgelt. You can set pceltFetched to NULL if celt is one. Otherwise, initialize the value of pceltFetched to 0 before calling this method.

Return value

S_OK is returned when the number of requested elements (celt) are returned successfully or the number of returned items (pceltFetched) is less than the number of requested elements.

Other success codes may be returned as a result of implementation. The following error codes are commonly returned on operation failure, but do not represent the only possible error values:

Return code	Description
E_POINTER	Pointer is not valid. Value: 0x80004003
E_OUTOFMEMORY	Failed to allocate the required memory. Value: 0x8007000E
E_INVALIDARG	One or more arguments are not valid. Value: 0x80070057

Remarks

If there are fewer than the requested number of elements left in the sequence, it retrieves the remaining elements.
