IWMDMStorageGlobals::GetStatus method (mswmdm.h)

  • Article

The GetStatus method retrieves the current status of a storage medium.

Syntax

HRESULT GetStatus(
  [out] DWORD *pdwStatus
);

Parameters

[out] pdwStatus

Pointer to a DWORD to receive the status information when the method returns. The following values can be returned in the pdwStatus parameter.

Status Description
WMDM_STATUS_READY The medium is in an idle or ready state.
WMDM_STATUS_BUSY An operation is ongoing. Evaluate status values to determine the ongoing operation.
WMDM_STATUS_STORAGE_NOTPRESENT The storage medium is not present. For devices with more than one medium supported, this value is only reported from the IWMDMStorageGlobals interface.
WMDM_STATUS_STORAGE_INITIALIZING The device is currently busy formatting a storage medium on a device.
WMDM_STATUS_STORAGE_BROKEN The storage medium is broken. For devices with more than one medium supported, this value is only reported from the IWMDMStorageGlobals interface.
WMDM_STATUS_STORAGE_NOTSUPPORTED The storage medium is not supported by the device. For devices with more than one medium supported, this value is only returned from the IWMDMStorageGlobals interface.
WMDM_STATUS_STORAGE_UNFORMATTED The storage medium is not formatted. For devices with more than one medium supported, this value is only reported from the IWMDMStorageGlobals interface.

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

This method must always be called before the caller attempts to interact with a storage medium. The status value retrieved is WMDM_STATUS_BUSY if some other interface has invoked an ongoing operation. You can evaluate the value retrieved from this call to determine whether an ongoing operation has been invoked from the IWMDMStorageGlobals interface.
