The ConvertInterfaceIndexToLuid function converts a local index 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.
InterfaceIndex [in] The local index value for the network interface.
InterfaceLuid [out] A pointer to the NET_LUID union for the network interface.
ConvertInterfaceIndexToLuid returns STATUS_SUCCESS if the function succeeds. If the function fails, the InterfaceLuid parameter is set to NULL, and ConvertInterfaceIndexToLuid returns the following error code:
| Return code | Description |
|---|---|
| STATUS_INVALID_PARAMETER | One of the parameters was invalid. ConvertInterfaceIndexToLuid returns this error if the InterfaceLuid parameter is NULL, or if the InterfaceIndex parameter is invalid. |
The ConvertInterfaceIndexToLuid function is protocol-independent and works with network interfaces for both the IPv6 and IPv4 protocols.
