CreateIpNetEntry2 function

The CreateIpNetEntry2 function creates a new neighbor IP address entry on the local computer.

Syntax


NETIOAPI_API CreateIpNetEntry2(
  _In_  const MIB_IPNET_ROW2 *Row
);

Parameters

Row [in]

A pointer to a MIB_IPNET_ROW2 structure entry for an IP route entry.

Return value

CreateIpNetEntry2 returns STATUS_SUCCESS if the function succeeds.

If the function fails, CreateIpNetEntry2 returns one of the following error codes:

Return codeDescription
STATUS_INVALID_PARAMETER

An invalid parameter was passed to the function. This error is returned if one of the following items occurs:

  • A NULL pointer is passed in the Row parameter.

  • The Address member of the MIB_IPNET_ROW2 structure that the Row parameter points to was not set to a valid unicast, anycast, or multicast IPv4 or IPv6 address.

  • The PhysicalAddress and PhysicalAddressLength members of the MIB_IPNET_ROW2 structure were not set to a valid physical address.

  • Both InterfaceLuid and InterfaceIndex members of the MIB_IPNET_ROW2 structure were unspecified.

  • A loopback address was passed in the Address member.

STATUS_NOT_FOUND

The specified interface could not be found. This error is returned if the function cannot find the network interface that is specified by the InterfaceLuid or InterfaceIndex member of the MIB_IPNET_ROW2 structure that the Row parameter points to.

STATUS_NOT_SUPPORTED

The request is not supported. This error is returned if no IPv4 stack is located on the local computer and an IPv4 address was specified in the Address member of the MIB_IPNET_ROW2 structure that the Row parameter points, or if no IPv6 stack is located on the local computer and an IPv6 address was specified in the Address member.

ERROR_OBJECT_ALREADY_EXISTS

The object already exists. This error is returned if the Address member of the MIB_IPNET_ROW2 structure that the Row parameter points to is a duplicate of an existing neighbor IP address on the interface that is specified by the InterfaceLuid or InterfaceIndex member of the MIB_IPNET_ROW2 structure.

Other

Use the FormatMessage function to obtain the message string for the returned error.

 

Remarks

Your driver must initialize the following members of the MIB_IPNET_ROW2 structure that the Row parameter points to:

  • Set the Address member to a valid unicast, anycast, or multicast IPv4 or IPv6 address and family.

  • Set the PhysicalAddress and PhysicalAddressLength members in the MIB_IPNET_ROW2 structure to a valid physical address.

  • Set InterfaceLuid or InterfaceIndex to the LUID or index value of the interface.

The InterfaceLuid and InterfaceIndex members are used in the order that is listed earlier. So if the InterfaceLuid is specified, this member is used to determine the interface to add the unicast IP address on. If no value was set for the InterfaceLuid member (the value of this member was set to zero), the InterfaceIndex member is next used to determine the interface.

The CreateIpNetEntry2 function fails if the IP address that is passed in the Address member of the MIB_IPNET_ROW2 structure that the Row parameter points to is a duplicate of an existing neighbor IP address on the interface.
