Previous: PEN Functions

This is general purpose function for registering callback
functions in LIBLINCKS. In principle there is the
following classes of callback functions going from the
highest level of abstraction down to low level communication
with database server:
- High level PEN (Parallel Editing Notification), see
section 7 for a more detailed description,
- Low level PEN, same events, with what set
to RCB_PEN, and
- Switching on/ off polling of PEN within LIBLINCKS,
see section 7 (this do not really fit in with the
callback functions, but based on the functionallity ...),
- When commands are sent to the DBS.
