This leads to an unreadable, but recoverable) media state.
Technically they are appendable although the last session
is not readable.
By default the open session gets closed here before the new
session is written. E.g. after writing a small dummy seesion
number 2 one can read session 1 and write session 3 which
points to data of session 1.
For the case that no media with 3 sessions is desired it is
possible to activate the following coarse single-session
closing code:
No new session will be written but calling programs will
report success. Quite misleading.
Activate only if really needed by

/* Close open session and media.
That was the goal of the failed run which led to the
unreadable (but recoverable) media state.
It is not easy to implement a general close function for
all media types. Therefore this pseudo write code is under
control of #ifdef.
