Article
02/22/2024

The Initialize method formats the storage medium.

Syntax

HRESULT Initialize(
  [in] UINT          fuMode,
  [in] IWMDMProgress *pProgress
);

Parameters

[in] fuMode

Mode used to initialize the medium. 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 returns immediately, and the operation is performed in a background thread.

[in] pProgress

Pointer to an IWMDMProgress interface implemented by an application to track the progress of the formatting operation.

Return value

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 extensive list of possible error codes, see Error Codes.

Remarks

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.
