ConvertInterfaceLuidToIndex function

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.

Syntax

NETIOAPI_API ConvertInterfaceLuidToIndex(
  _In_  const NET_LUID     *InterfaceLuid,
  _Out_       PNET_IFINDEX InterfaceIndex
);

Parameters

  • InterfaceLuid [in]
    A pointer to a NET_LUID union for the network interface.

  • InterfaceIndex [out]
    The local index value for the network interface.

Return value

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.

Remarks

The ConvertInterfaceLuidToIndex function is protocol-independent and works with network interfaces for both the IPv6 and IPv4 protocols.
