IVdsAsync::Cancel method (vds.h)

  • Article

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Cancels the asynchronous operation.

Syntax

HRESULT Cancel();

Return value

This method can return standard HRESULT values, such as E_OUTOFMEMORY, and VDS-specific return values. It can also return converted system error codes using the HRESULT_FROM_WIN32 macro. Errors can originate from VDS itself or from the underlying VDS provider that is being used. Possible return values include the following.

Return code/value Description
VDS_E_NOT_SUPPORTED
0x80042400L
 The method is not supported. Neither the basic provider nor the current dynamic provider support this method.
VDS_E_OPERATION_CANCELED
0x8004240DL
 The operation has already been canceled.
VDS_E_CANCEL_TOO_LATE
0x8004240CL
 The operation has progressed too far to cancel.
VDS_E_INCOMPATIBLE_FILE_SYSTEM
0x80042425L
 The file system is incompatible with the specified operation.
VDS_E_INCOMPATIBLE_MEDIA
0x80042426L
 The media is incompatible with this operation.
VDS_E_ACCESS_DENIED
0x80042427L
 Access is denied. An application using VDS must run under the Backup Operator or Administrators group account.

Remarks

Dynamic providers do not implement this method. The basic provider checks for this method only when cleaning a disk and does not implement it for any other operation.
