GetIpNetEntry2 (NETIOAPI) (Compact 2013)

  • Artigo

3/26/2014

This function retrieves information for a neighbor IP address entry on the local device.

Syntax

NETIOAPI_API
  GetIpNetEntry2(
    IN OUT PMIB_IPNET_ROW2  Row
    );

Parameters

  • Row
    A pointer to a MIB_IPNET_ROW2 structure entry for a neighbor IP address entry. On successful return, this structure is updated with the properties for neighbor IP address.

Return Value

GetIpNetEntry2 returns STATUS_SUCCESS if the function succeeds.

If the function fails, GetIpNetEntry2 returns one of the following error codes:

Error Code

Meaning

STATUS_INVALID_PARAMETER

An invalid parameter was passed to the function. This error is returned if 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 neighbor IPv4 or IPv6 address, or both InterfaceLuid and InterfaceIndex members of the MIB_IPNET_ROW2 structure were unspecified.

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 device and an IPv4 address was specified in the Address member of the MIB_IPNET_ROW2 structure that the Row parameter points to, or if no IPv6 stack is located on the local device and an IPv6 address was specified in the Address member.

Other

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

Remarks

The GetIpNetEntry2 function is used to retrieve a MIB_IPNET_ROW2 structure entry.

On input, your driver must initialize the following members of the MIB_IPNET_ROW2 structure that the Row parameter points to.

  • Address
    Set to a valid neighbor IPv4 or IPv6 address and family.
  • InterfaceLuid or InterfaceIndex
    These members are used in the order that is listed earlier. So if InterfaceLuid is specified, this member is used to determine the interface. 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.

On output, when the call is successful, GetIpNetEntry2 retrieves the other properties for the neighbor IP address and fills in the MIB_IPNET_ROW2 structure that the Row parameter points to.

Your driver can call the GetIpNetTable2 (NETIOAPI) function to enumerate the neighbor IP address entries on a local device.
