Data Source Plug-in Interfaces

You can create a data source plug-in by using methods in the following interfaces.

Interface	Description
IWMSBasicPlugin	Contains methods to initialize, enable, and shut down a plug-in. It is recommended that all custom plug-ins implement this interface.
IWMSDataContainer	Retrieves an optimal buffer size and offset, and reads data from a source into the buffer. This interface is implemented by a data source plug-in and called by the server.
IWMSDataContainerCallback	Contains callback methods for the IWMSDataContainer interface. The callback interface is implemented by the server and called by a data source plug-in.
IWMSDataSourcePlugin	Contains methods to open a data container or a directory. This interface is implemented by a data source plug-in and called by the server.
IWMSDataSourcePluginCallback	Contains callback methods for the IWMSDataSourcePlugin interface. The callback interface is implemented by the server and called by a data source plug-in.
IWMSDirectory	Retrieves directory information. This interface is implemented by a data source plug-in and called by the server.
IWMSPacketStreamDataContainer	Contains methods to notify the server of stream signals and to determine the maximum packet size used by a data container. This interface is implemented by a data source plug-in and called by the server.
IWMSPacketStreamer	Contains methods for retrieving information on streams being sent down a data path and for controlling the streams being sent down a data path. This interface is implemented by a data source plug-in and called by the server.
IWMSPacketStreamerCallback	Contains callback methods for the IWMSPacketStreamer interface. The callback interface is implemented by the server and called by a data source plug-in.
IWMSPushSource	Contains methods that control the flow of data through a data path. This interface is implemented by a data source plug-in and called by the server.
IWMSPushSourceCallback	Contains callback methods for the IWMSPushSource interface. The callback interface is implemented by the server and called by a data source plug-in.
