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