Syntax

HRESULT MergeTo(
  [in]          BSTR           newDiskImagePath,
  [in]          VMHardDiskType newDiskImageType,
  [out, retval] IVMTask        **mergeTask
);

Parameters

newDiskImagePath [in]

The path to the new target disk image where the selected disk images will be merged.

newDiskImageType [in]

The type of new target disk image. The image types allowed for the new target disk image are vmDiskType_Dynamic and vmDiskType_FixedSize. For more information, see VMHardDiskType.

mergeTask [out, retval]

An IVMTask object that is used to track the completion of the merging process.
