ConvertInterfaceGuidToLuid function

The ConvertInterfaceGuidToLuid function converts a globally unique identifier (GUID) for a network interface to the locally unique identifier (LUID) for the interface.

Note  The ConvertInterfaceXxx API family enumerates identifiers over all interfaces bound to TCP/IP, which may include virtual miniports, lightweight filters, tunnel adapters, and physical interfaces.

Syntax


NETIOAPI_API ConvertInterfaceGuidToLuid(
  _In_   const GUID *InterfaceGuid,
  _Out_  PNET_LUID InterfaceLuid
);

Parameters

InterfaceGuid [in]

A pointer to a GUID for the network interface.

InterfaceLuid [out]

A pointer to the NET_LUID union for the network interface.

Return value

ConvertInterfaceGuidToLuid returns STATUS_SUCCESS if the function succeeds. If the function fails, the InterfaceLuid parameter is set to NULL, and ConvertInterfaceGuidToLuid returns the following error code:

Return codeDescription
STATUS_INVALID_PARAMETER
