The Rename method renames the current storage.

Syntax

HRESULT Rename(
UINTfuMode,
LPWSTR  pwszNewName,IWMDMProgress*pProgress
);

Parameters

fuMode

[in]  Processing mode used for the Rename operation. Specify exactly one of the following two modes. If both modes are specified, block mode is used.

Mode Description
WMDM_MODE_BLOCK The operation is performed using block mode processing. The call will not return until the operation is finished.
WMDM_MODE_THREAD The operation is performed using thread mode processing. The call will return immediately, and the operation is performed in a background thread.

pwszNewName

[in]  Pointer to a wide-character null-terminated string specifying the new name.

pProgress

[in]  Optional pointer to an IWMDMProgress interface that has been implemented by the application to track the progress of the action.

Return Values

The method returns an HRESULT. All the interface methods in Windows Media Device Manager can return any of the following classes of error codes:

  • Standard COM error codes
  • Windows error codes converted to HRESULT values
  • Windows Media Device Manager error codes

For an extenstive list of possible error codes, see Error Codes.

Possible values include, but are not limited to, those in the following table.

Return code Description
S_OK The method succeeded.
WMDM_E_NOTSUPPORTED Renaming is not supported for this storage medium.
WMDM_E_INTERFACEDEAD The file or folder was previously deleted.
E_BUSY The media device is already busy with another operation.
E_INVALIDARG One or more parameters is invalid or NULL.
E_FAIL An unspecified error occurred.
WMDM_E_NOTCERTIFIED The caller is not certified

Remarks

If the WMDM_MODE_THREAD flag is specified, you should obtain completion status by calling either IWMDMProgress2::End2 or IWMDMProgress3::End3. These methods will ensure that the operation is complete and will also return an HRESULT with success or failure information.

If an application uses WMDM_MODE_THREAD and passes a non-null pProgress parameter, the application must ensure that the object to which pProgress belongs is not destroyed until the read operation completes, because Windows Media Device Manager will send progress notifications to this object. This object can be destroyed only after it receives an End notification. Failure to do this will result in access violations.
