3.1.4.12 IImport

  • Article

The IImport interface provides methods for importing, as specified in Export and Import (section 1.3.7), conglomerations and partitions from installer package files and returning information about installer package files. This interface inherits from IUnknown, as specified in [MS-DCOM] section 3.1.1.5.8.

To receive incoming remote calls for this interface, the server MUST implement a DCOM Object Class with the CLSID CLSID_COMAServer (see section 1.9) using the UUID {C2BE6970-DF9E-11D1-8B87-00C04FD7A924} for this interface.

This interface includes the following methods beyond those of IUnknown.
