/* This routine is called after the library has been loaded into

must initialize those parts of the base data structure which
have not been set up yet. As of Kickstart 2.0 the setup code
in ROM will have initialized the entire Library structure with
the exception of the lib_Revision field, i.e. everything that
could be gained from the Resident structure is now in the
Library structure. Earlier operating system releases would leave
the entire Library structure uninitialized. For this example
we assume that Kickstart 2.0 is around as it must be possible
to open dos.library V37.
The library initialization is single threaded, i.e. the operating
system processes library initialization in a queue. The longer it
takes for the following routine to set up the base data structure,
the longer will other Tasks and Processes have to wait to get their
disk resident libraries opened. This means, the initialization code
has to be as brief as possible. This particular example code opens
ROM resident libraries here, which is permitted. You should not
open disk resident libraries and devices or do anything else that
could take a long time to complete (in this context "long" is anything
that takes up a second or longer).
This routine must return the Library base pointer if it succeeds.
