ConvertInterfaceLuidToNameA (Compact 2013)

3/26/2014

This function converts a locally unique identifier (LUID) for a network interface to the ANSI interface name.

Syntax

NETIO_STATUS WINAPI ConvertInterfaceLuidToNameA(
  __in   const NET_LUID* InterfaceLuid,
  __out  PSTR InterfaceName,
  __in   SIZE_T Length
);

Parameters

• InterfaceLuid
  A pointer to a NET_LUID for a network interface.

• InterfaceName
  A pointer to a buffer to hold the NULL-terminated ANSI string that contains the interface name when the function returns successfully.

• Length
  The length, in bytes, of the buffer pointed to by the InterfaceName parameter. This value must be large enough to accommodate the interface name and the terminating null character. The maximum required length is NDIS_IF_MAX_STRING_SIZE + 1.

Return Value

On success, ConvertInterfaceLuidToNameA returns NETIO_ERROR_SUCCESS. Any nonzero return value indicates failure.

Error code	Meaning
ERROR_INVALID_PARAMETER	One of the parameters was invalid. This error is returned if either the InterfaceLuid or the InterfaceName parameter was NULL or if the InterfaceLuid parameter was invalid.
ERROR_NOT_ENOUGH_MEMORY	Not enough storage is available to process this command. This error is returned if the size of the buffer pointed to by InterfaceName parameter was not large enough as specified in the Length parameter to hold the interface name.

Remarks

The ConvertInterfaceLuidToNameA function is protocol independent and works with network interfaces for both the IPv6 and IPv4 protocol. The ConvertInterfaceLuidToNameA converts a network interface LUID to an ANSI interface name.

The ConvertInterfaceLuidToNameW converts a network interface LUID to a Unicode interface name.

The maximum length of an interface name, NDIS_IF_MAX_STRING_SIZE, without the terminating NULL is declared in the Ntddndis.h header file. The NDIS_IF_MAX_STRING_SIZE is defined to be the IF_MAX_STRING_SIZE constant defined in the Ifdef.h header file. The Ntddndis.h and Ifdef.h header files are automatically included in the Netioapi.h header file which is automatically included by the Iphlpapi.h header file. The Ntddndis.h, Ifdef.h, and Netioapi.h header files should never be used directly.
