The Dhcpv6RenewPrefix function renews a prefix previously acquired with the Dhcpv6RequestPrefix function.

Syntax

DWORD APIENTRY Dhcpv6RenewPrefix(
  __in     LPWSTR adapterName,
  __in     LPDHCPV6CAPI_CLASSID classId,
  __inout  LPDHCPV6PrefixLeaseInformation prefixleaseInfo,
  __out    DWORD pdwTimeToWait,
  __in     DWORD bValidatePrefix
);

Parameters

adapterName [in]

Name of the adapter on which the prefix renewal must be sent.

classId [in]

Pointer to a DHCPV6CAPI_CLASSID structure that contains the binary ClassId information to send on the wire.

Note  DHCPv6 Option Code 15 (0x000F) is not supported by this API. Typically, the User Class option is used by a client to identify the type or category of user or application it represents. A server selects the configuration information for the client based on the classes identified in this option.

prefixleaseInfo [in, out]

Pointer to a DHCPV6PrefixLeaseInformation structure that contains the prefix lease information.

pdwTimeToWait [out]

Contains the number of seconds a requesting application needs to wait before calling the Dhcpv6RenewPrefix function to renew its acquired prefixes. A value of 0xFFFFFFFF indicates that the application does not need to renew its lease.

bValidatePrefix [in]

Specifies to the DHCPv6 client whether or not to send a REBIND in order to validate the prefix bindings. TRUE indicates that a REBIND is required. FALSE indicates RENEW is required.

Return Value

Returns ERROR_SUCCESS upon successful completion.
