/*
j939pro.h

This header file contains the prototypes for the J1939 library routines.
These cannot be in j1939_16.h because the pointers to the user
message buffers must specify whether they are in banks 0/1 or
banks 2/3 with the J1939_USER_MSG_BANK definition, which is defined in
j1939cfg.h.

The global variable declarations are also included here, mostly to reduce
the risk that someone will accidentally change them.

This header file is automatically included by including j1939cfg.h.
