The GetAnycastIpAddressEntry function retrieves information for an existing anycast IP address entry on a local computer.
NETIOAPI_API GetAnycastIpAddressEntry( _Inout_ PMIB_ANYCASTIPADDRESS_ROW Row );
- Row [in, out]
A pointer to a MIB_ANYCASTIPADDRESS_ROW structure entry for an anycast IP address entry. On successful return, this structure is updated with the properties for an existing anycast IP address.
GetAnycastIpAddressEntry returns STATUS_SUCCESS if the function succeeds.
If the function fails, GetAnycastIpAddressEntry returns one of the following error codes:
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 structure that the Row parameter points to was not set to a valid anycast IPv4 or IPv6 address, or both InterfaceLuid and InterfaceIndex members of the MIB_ANYCASTIPADDRESS_ROW structure were unspecified.
The specified interface could not be found. This error is returned if the function cannot find the network interface that specified by the InterfaceLuid or InterfaceIndex member of the MIB_ANYCASTIPADDRESS_ROW structure that the Row parameter points to.
The request is not supported. This error is returned if no IPv4 stack is located on the local computer and an IPv4 address was specified in the Address member of the MIB_UNICASTIPADDRESS_ROW structure that the Row parameter points to, or if no IPv6 stack is located on the local computer and an IPv6 address was specified in the Address member.
Use the FormatMessage function to obtain the message string for the returned error.
The GetAnycastIpAddressEntry function is used to retrieve an existing MIB_ANYCASTIPADDRESS_ROW structure entry.
On input, your driver must initialize the following members of the MIB_ANYCASTIPADDRESS_ROW structure that the Row parameter points to.
Set to a valid IPv4 or IPv6 anycast address and family.
InterfaceLuid or InterfaceIndex
These members are used in the order that is listed earlier. So if InterfaceLuid is specified, this member is used to determine the interface. If no value was set for the InterfaceLuid member (the value 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 that the Row parameter points to.
Your driver can call the GetAnycastIpAddressTable function to enumerate the anycast IP address entries on a local computer.
Available in Windows Vista and later versions of the Windows operating systems.
