IMDSPStorageGlobals::Initialize method (mswmdm.h)

Article
07/27/2022

The Initialize method formats the storage medium. This method is optional. However, this method should be implemented if the device supports this functionality. If this method is not implemented, IMDSPStorageGlobals::GetCapabilities must return WMDM_STORAGECAP_NOT_INITIALIZABLE in addition to any other flags. For more information, see Mandatory and Optional Interfaces.

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 is not returned 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. This parameter can be NULL.

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 WMDM_MODE_BLOCK is specified, Initialize does not return until formatting is finished. If the WMDM_MODE_THREAD is specified, the call returns immediately and the caller can use the IMDSPStorageGlobals::GetStatus method to track the initializing operation.
