Programming with the X/Open Transport Interface (XTI)

State transitions

The Transport Interface has two components:

the library routines that provide the transport services to users
the state transition rules that define the sequence in which the transport routines may be invoked

The state transition rules can be found later in the state tables in ``State transitions''. The state tables define the legal sequence of library calls based on state information and the handling of events. These events include user-generated library calls, as well as provider-generated event indications.

NOTE: Any user of the Transport Interface should completely understand all possible state transitions before writing software using the interface.
