FlushIpNetTable2 (NETIOAPI) (Compact 2013)

This function flushes the IP neighbor table on a local device.

Syntax

NETIOAPI_API
  FlushIpNetTable2(
    IN ADDRESS_FAMILY  Family,
    IN NET_IFINDEX  InterfaceIndex
    );

Parameters

  • Family
    The address family to flush.

    Possible values for the address family are listed in the Winsock2.h header file. Note that the values for the AF_ address family and PF_ protocol family constants are identical (for example, AF_INET and PF_INET). Therefore, you can use either constant.

    The following values are currently supported for the address family:

    • AF_UNSPEC
      The address family is unspecified. When this value is specified, this function flushes the neighbor IP address table that contains both IPv4 and IPv6 entries.
    • AF_INET
      The IPv4 address family. When this value is specified, this function flushes the neighbor IP address table that contains only IPv4 entries.
    • AF_INET6
      The IPv6 address family. When this value is specified, this function flushes the neighbor IP address table that contains only IPv6 entries.
  • InterfaceIndex
    The interface index. If the index is specified, the function flushes the neighbor IP address entries on a specific interface. Otherwise, the function flushes the neighbor IP address entries on all the interfaces. To ignore the interface, set this parameter to zero.

Return Value

FlushIpNetTable2 returns STATUS_SUCCESS if the function succeeds.

If the function fails, FlushIpNetTable2 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 the Family parameter was not specified as AF_INET, AF_INET6, or AF_UNSPEC.

STATUS_NOT_SUPPORTED

The request is not supported. This error is returned if no IPv4 stack is located on the local device and AF_INET was specified in the Family parameter, or if no IPv6 stack is located on the local device and AF_INET6 was specified in the Family parameter.

Other

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

Remarks

The FlushIpNetTable2 function flushes or deletes the neighbor IP addresses on a local device. Your driver can use the Family parameter to limit neighbor IP addresses to delete to a particular IP address family. If neighbor IP addresses for both IPv4 and IPv6 should be deleted, your driver should set the Family parameter to AF_UNSPEC. Your driver can use the InterfaceIndex parameter to limit neighbor IP addresses to delete to a particular interface. If neighbor IP addresses for all interfaces should be deleted, your driver should set the InterfaceIndex parameter to zero.

Your driver must initialize the Family parameter to AF_INET, AF_INET6, or AF_UNSPEC.
