GetIpNetEntry2 (Compact 7)
3/12/2014
This function retrieves information for a neighbor IP address entry on the local device.
Syntax
NETIOAPI_API GetIpNetEntry2(
__inout 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 will be updated with the properties for neighbor IP address.
Return Value
If the function succeeds, the return value is NO_ERROR.
If the function fails, the return value is one of the following error codes.
| Return code | Description |
|---|---|
ERROR_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 pointed to by the Row parameter was not set to a valid neighbor IPv4 or IPv6 address, or both the InterfaceLuid or InterfaceIndex members of the MIB_IPNET_ROW2 pointed to by the Row parameter were unspecified. |
ERROR_NOT_FOUND |
The specified interface could not be found. This error is returned if the network interface specified by the InterfaceLuid or InterfaceIndex member of the MIB_IPNET_ROW2 pointed to by the Row parameter could not be found. |
ERROR_NOT_SUPPORTED |
The request is not supported. This error is returned if no IPv4 stack is on the local device and an IPv4 address was specified in the Address member of the MIB_IPNET_ROW2 structure pointed to by the Row parameter. This error is also returned if no IPv6 stack is on the local device and an IPv6 address was specified in the Address member of the MIB_IPNET_ROW2 structure. |
Other |
Use FormatMessage 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, the Address member in the MIB_IPNET_ROW2 structure pointed to by the Row parameter must be initialized to a valid neighbor IPv4 or IPv6 address and family. In addition, at least one of the following members in the MIB_IPNET_ROW2 structure pointed to the Row parameter must be initialized: the InterfaceLuid or InterfaceIndex. The fields are used in the order listed earlier. So if the InterfaceLuid is specified, this member is used to determine the interface. If no value was set for the InterfaceLuid member (the values 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 out the MIB_IPNET_ROW2 structure pointed to by the Row parameter.
The GetIpNetTable2 function can be called to enumerate the neighbor IP address entries on a local device.
