FlushIpPathTable (NETIOAPI) (Compact 2013)

  • [アーティクル]

3/26/2014

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

Syntax

NETIOAPI_API
  FlushIpPathTable(
    IN ADDRESS_FAMILY  Family
    );

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.

    On later versions of the Windows operating systems, possible values for the Family parameter are defined in the Ws2def.h header file. Note that the Ws2def.h header file is automatically included in Netioapi.h and you should never use Ws2def.h directly.

    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 IP path table that contains both IPv4 and IPv6 entries.
    • AF_INET
      The IPv4 address family. When this value is specified, this function flushes the IP path table that contains only IPv4 entries.
    • AF_INET6
      The IPv6 address family. When this value is specified, this function flushes the IP path 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

Error Code

Meaning

STATUS_SUCCESS

The function succeeds

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 FlushIpPathTable function flushes or deletes the IP path entries on a local device. Your driver can use the Family parameter to limit the IP path entries to delete to a particular IP address family. If IP path entries for both IPv4 and IPv6 should be deleted, your driver should set the Family parameter to AF_UNSPEC.

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