The Next method retrieves a pointer to the next IWMDMStorage or IWMDMDevice interface.
Syntax
HRESULT Next(
ULONG celt,
IWMDMStorage** ppStorage,
ULONG* pceltFetched
);
Parameters
celt
[in] Number of storages requested.
ppStorage
[out] Pointer to a storage device.
pceltFetched
[out] Number of storage devices enumerated.
Return Values
If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.
| Return code | Description |
| S_FALSE | No more storage devices exist. |
| E_INVALIDARG | A parameter is invalid or is a NULL pointer. |
| E_FAIL | An unspecified error occurred. |
Remarks
The Windows NT 4.0 operating system cannot detect when a user physically disconnects a device. Therefore, when a device is disconnected, the Next method does not return zero in pceltFetched or NULL in ppStorage.
