t * Dhcp_wire.pktcreate xid mac returns a pair of t, buffer. t represents the current * state of the client in the lease transaction, and buffer is the suggested * next packet the caller should take to progress toward accepting a lease. * The argument xid allows the caller to specify a transaction ID * to use for the lease attempt. * requests is a list of option codes which the client should ask for in its * attempt to get a DHCP lease. If requests is not given, we'll make an educated * guess rather than requesting nothing.
val input :
t ->
Cstruct.t ->
[ `Response of t * Dhcp_wire.pkt | `New_lease of t * Dhcp_wire.pkt | `Noop ]input t buf attempts to advance the state of t * with the contents of buf. If buf is invalid or not useful given * the current state of t, `Noop is returned indicating no action should be taken. * Otherwise, either a `Response will be suggested along with a t whose state has been advanced, * or a `New_lease will be returned along with a t whose state has been advanced.
val lease : t -> Dhcp_wire.pkt optionlease t will return Some lease if t has succeeded in * completing a lease transaction with some server. * Note that the library has no sense of the passage of time, so expiration * is not considered; there is no guarantee that Some lease is still * valid on the network. The caller is responsible for keeping track of * the time at which the lease was obtained, and renewing the lease when * necessary. * If t hasn't yet completed a lease transaction, None will be returned.
val renew : t -> [ `Response of t * Dhcp_wire.pkt | `Noop ]renew t returns either a `Response with the next state and suggested action * of the client attempting to renew t's lease, * or `Noop if t does not have a lease and therefore can't be renewed.
