ConvertInterfaceAliasToLuid function

The ConvertInterfaceAliasToLuid function converts an interface alias name 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 ConvertInterfaceAliasToLuid(
  _In_  const WCHAR     *InterfaceAlias,
  _Out_       PNET_LUID InterfaceLuid
);

Parameters

  • InterfaceAlias [in]
    A pointer to a NULL-terminated Unicode string that contains the alias name of the network interface.

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

Return value

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

Return code Description
STATUS_INVALID_PARAMETER

One of the parameters was invalid. ConvertInterfaceAliasToLuid returns this error if either InterfaceAlias or InterfaceLuid is NULL, or if InterfaceAlias is invalid.

Remarks

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