(All fields are exposed such that if a wrapper needs to dup the storage as it passes

+ NOTE:
+ State is the RMR state of processing on the message. The transport state (tp_state)
+ will be set to mirror the value of errno for wrappers unable to access errno directly,
+ but will only be set if state is not RMR_OK. Even then, the value may be suspect as
+ the underlying transport mechanism may not set errno. It is strongly recommended that
