GetAnycastIpAddressEntry (Compact 2013)
3/26/2014
This function retrieves information for an existing anycast IP address entry on the local device.
Syntax
NETIOAPI_API GetAnycastIpAddressEntry(
__inout PMIB_ANYCASTIPADDRESS_ROW Row
);
Parameters
- Row
A pointer to a MIB_ANYCASTIPADDRESS_ROW structure entry for an anycast IP address entry. On successful return, this structure will be updated with the properties for an existing anycast 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_ANYCASTIPADDRESS_ROW pointed to by the Row parameter was not set to a valid anycast IPv4 or IPv6 address, or both the InterfaceLuid or InterfaceIndex members of the MIB_ANYCASTIPADDRESS_ROW 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_ANYCASTIPADDRESS_ROW 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 located on the local device and an IPv4 address was specified in the Address member MIB_UNICASTIPADDRESS_ROW pointed to by the Row parameter. This error is returned if no IPv6 stack is located on the local device and an IPv6 address was specified in the Address member. |
Other |
Use FormatMessage to obtain the message string for the returned error. |
Remarks
The GetAnycastIpAddressEntry function is used to retrieve an existing MIB_ANYCASTIPADDRESS_ROW structure entry.
On input, the Address member in the MIB_ANYCASTIPADDRESS_ROW structure pointed to by the Row parameter must be initialized to a valid anycast IPv4 or IPv6 address and family. In addition, at least one of the following members in the MIB_ANYCASTIPADDRESS_ROW structure pointed to the Row parameter must be initialized: the InterfaceLuid or InterfaceIndex. The fields are used in the order listed above. 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, GetAnycastIpAddressEntry retrieves the other properties for the anycast IP address and fills out the MIB_ANYCASTIPADDRESS_ROW structure pointed to by the Row parameter.
The GetAnycastIpAddressTable function can be called to enumerate the anycast IP address entries on a local device.
