IWMDMOperation::GetObjectTotalSize

The GetObjectTotalSize method retrieves the total size of an object, in bytes.

Syntax

HRESULT GetObjectTotalSize(
  DWORD*  pdwSize,
  DWORD*  pdwSizeHigh
);

Parameters

pdwSize

[out] Pointer to a double word containing the low-order bits of the object size, in bytes.

pdwSizeHigh

[out] Pointer to a double word containing the high-order bits of the object size, in bytes.

Return Values

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.

Return code	Description
WMDM_E_USER_CANCELLED	The application instructs Windows Media Device Manager to cancel the current operation without waiting for it to finish.
E_FAIL	An unspecified error occurred.

Remarks

This method is called after the GetObjectAttributes method has been called. When transferring, you are passed the total size of the content being sent.

If either E_FAIL or WMDM_E_USER_CANCELLED is returned from this call, the operation is cancelled and the End method is called. If the application is using block mode and returns WMDM_E_USER_CANCELLED, then Windows Media Device Manager will return this same error to the application.
