IWDFDeviceAssignTransportSettings::AssignCompositeInstanceID method

[Warning: UMDF 2 is the latest version of UMDF and supersedes UMDF 1. All new UMDF drivers should be written using UMDF 2. No new features are being added to UMDF 1 and there is limited support for UMDF 1 on newer versions of Windows 10. Universal Windows drivers must use UMDF 2. For more info, see Getting Started with UMDF.]

A transport driver's call to the AssignCompositeInstanceID method assigns an instance identifier (ID) to the logical composite device to which the transport is attached.

Syntax

HRESULT AssignCompositeInstanceID(
  [in] PCWSTR pcwszInstanceID
);

Parameters

• pcwszInstanceID [in]
  A pointer to a caller-supplied, null-terminated character string that represents an instance ID.

Return value

AssignCompositeInstanceID return S_OK if the operation succeeds. Otherwise, this method returns one of the error codes that are defined in Winerror.h.

Remarks

Future versions of the framework might not support the IWDFDeviceAssignTransportSettings interface. Drivers for multi-transport devices should use Windows Portable Devices (WPD) interfaces, which are described in another section of this WDK documentation.

The WDK does not provide a header that defines the IWDFDeviceAssignTransportSettings interface. For information about the interface definition language (IDL) definition of this interface, see IWDFDeviceAssignTransportSettings.
