SHCEntryPoint

As illustrated in the following example, a DLL stream handler implements function through an additional entry point. DLL stream handlers must supply an interface to communicate with the Sync/Stream Manager. This interface, called the stream handler command (SHC) interface, exports stream handler commands (SHCs) for use by the Sync/Stream Manager to set up and control data streams. These SHCs are accessible through a single entry point, SHCEntryPoint.
