3/12/2014

This function initializes a MIB_IPFORWARD_ROW2 structure with default values for an IP route entry on a local device.

Syntax

VOID NETIOAPI_API_
  InitializeIpForwardEntry(
    OUT PMIB_UNICASTIPADDRESS_ROW  Row
    );

Parameters

  • Row
    On entry, a pointer to a MIB_IPFORWARD_ROW2 structure entry for an IP route entry.

    On return, the MIB_IPFORWARD_ROW2 structure that this parameter points to is initialized with default values for an IP route entry.

Return Value

None

Remarks

Your driver must use the InitializeIpForwardEntry function to initialize the members of a MIB_IPFORWARD_ROW2 structure entry with default values for an IP route entry for later use with the CreateIpForwardEntry2 (NETIOAPI) function.

On input, your driver must pass InitializeIpForwardEntry a new MIB_IPFORWARD_ROW2 structure to initialize.

On output, the members of the MIB_IPFORWARD_ROW2 structure that the Row parameter points to are initialized as follows.

  • ValidLifetime and PreferredLifetime
    Set to an infinite value.
  • Loopback, AutoconfigureAddress, Publish, and Immortal
    Set to TRUE.
  • SitePrefixLength, Metric, and Protocol
    Set to illegal values.
  • All other members
    Set to zero.

After a driver calls InitializeIpForwardEntry, the driver can then change the members in the MIB_IPFORWARD_ROW2 entry that it wants to modify, and then call the CreateIpForwardEntry2 to add the new IP route entry to the local device.
