58 * wtp_init_machine.def: macro call for generating WTP initiator state
59 * machine. See the architecture document for guidance how to use and update
62 * By Aarno Syvänen for Wapit Ltd.
64 * WTPRespMachine data structure includes current state of WTP responder state
65 * machine for a specific transaction. This means all data needed to handle at
66 * least two incoming events of a certain transaction. Its fields can be
67 * grouped following way:
69 * General: a) wtp initiator machine state
70 * b) tidnew flag, telling whether tid is wrapped up
72 * Fields telling the service required:
73 * a) transaction class (is transaction confirmed or not)
74 * b) user acknowledgement flag (do we wait for response
75 * primitive of WTP user (for instance, WSP) or not)
77 * Machine identification: address four-tuple and transaction identifier
79 * Fields required for reliable transmission:
80 * a) pointer to the timer of this machine in the timers list
81 * b) counter for retransmissions
82 * c) flag telling are we resending ack pdu doing tid verifica-
84 * d) packed invoke message, for greater effectivity
