GetIpInterfaceEntry (NETIOAPI) (Compact 2013)

  • [アーティクル]

3/26/2014

This function retrieves IP information for the specified interface on a local device.

Syntax

NETIOAPI_API
  GetIpInterfaceEntry(
    IN OUT PMIB_IPINTERFACE_ROW  Row
    );

Parameters

  • Row
    A pointer to a MIB_IPINTERFACE_ROW structure that, on successful return, receives information for an interface on the local device. On input, your driver must set the InterfaceLuid member or the InterfaceIndex member of the MIB_IPINTERFACE_ROW to the interface to retrieve information for.

Return Value

Error Code

Meaning

STATUS_SUCCESS

The function succeeds.

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 Family member of the MIB_IPINTERFACE_ROW structure that the Row parameter points to was not specified as AF_INET or AF_INET6, or the InterfaceLuid and InterfaceIndex members of the MIB_IPINTERFACE_ROW 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_IPINTERFACE_ROW structure that the Row parameter points to.

Other

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

Remarks

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

  • Family
    Set to either AF_INET or AF_INET6.
  • 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, GetIpInterfaceEntry fills in the remaining members of the MIB_IPINTERFACE_ROW structure that the Row parameter points to.

Your driver must use the InitializeIpInterfaceEntry (NETIOAPI) function to initialize the fields of a MIB_IPINTERFACE_ROW structure entry with default values. A driver can then change the fields in the MIB_IPINTERFACE_ROW entry that it wants to modify, and then call the SetIpInterfaceEntry (NETIOAPI) function.
