DeleteUnicastIpAddressEntry (NETIOAPI) (Compact 7)

3/12/2014

This function deletes an existing unicast IP address entry on a local device.

Syntax

NETIOAPI_API
  DeleteUnicastIpAddressEntry(
    IN const MIB_UNICASTIPADDRESS_ROW*  Row
    );

Row
A pointer to a MIB_UNICASTIPADDRESS_ROW structure entry for an existing unicast IP address entry to delete from the local device.

DeleteUnicastIpAddressEntry returns STATUS_SUCCESS if the function succeeds.

If the function fails, DeleteUnicastIpAddressEntry returns one of the following error codes:

Error Code	Meaning
STATUS_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_UNICASTIPADDRESS_ROW structure that the Row parameter points to was not set to a valid unicast IPv4 or IPv6 address, or both InterfaceLuid and InterfaceIndex members of the MIB_UNICASTIPADDRESS_ROW structure were unspecified.
STATUS_NOT_FOUND	The specified interface could not be found. This error is returned if the function cannot find the network interface that is specified by the InterfaceLuid or InterfaceIndex member of the MIB_UNICASTIPADDRESS_ROW structure that the Row parameter points to.
STATUS_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 of the MIB_UNICASTIPADDRESS_ROW structure that the Row parameter points to, or if no IPv6 stack is located on the local device and an IPv6 address was specified in the Address member.
Other	Use the FormatMessage function to obtain the message string for the returned error.

The DeleteUnicastIpAddressEntry function is used to delete an existing MIB_UNICASTIPADDRESS_ROW structure entry on the local device.

On input, your driver must initialize the following members of the MIB_UNICASTIPADDRESS_ROW structure that the Row parameter points to.

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.

If the function is successful, the existing IP address that the Row parameter represents is deleted.

Your driver can call the GetUnicastIpAddressTable (NETIOAPI) function to enumerate the unicast IP address entries on a local device. Your driver can call the GetUnicastIpAddressEntry (NETIOAPI) function to retrieve a specific existing unicast IP address entry.
