IEnumUnknown::Next method (objidl.h)
Retrieves the specified number of items in the enumeration sequence.
HRESULT Next( [in] ULONG celt, [out] IUnknown **rgelt, [out] ULONG *pceltFetched );
The number of items to be retrieved. If there are fewer than the requested number of items left in the sequence, this method retrieves the remaining elements.
An array of enumerated items.
The enumerator is responsible for calling AddRef, and the caller is responsible for calling Release through each pointer enumerated. If celt is greater than 1, the caller must also pass a non-NULL pointer passed to pceltFetched to know how many pointers to release.
The number of items that were retrieved. This parameter is always less than or equal to the number of items requested.
If the method retrieves the number of items requested, the return value is S_OK. Otherwise, it is S_FALSE.
