NAME DHCP server termination callback routine
SYNOPSIS DHCP server termination callback routine. This callback \
will be called by DHCP server upon termination of the DHCP \

shutdown so that the lease can later be restored. The \
DHCPS_INSTALL_CALLBACK_HOOK must also be set to TRUE in \
order to install this callback hook.

* on a packet socket using the clients link-layer address.but when
* it comes to INFORM MESSAGE, udp socket is a better choice.

* Parameters: handle - pointer to ipdhcps handle
* Returns: number of bytes sent. -1 if something failed.
