No, these are not what I'm looking for.  From the original post for this 
thread:

I need to do direct-access I/O from a Modula 3 program with a file
format that is externally specified.  It is necessary to both read and
write in random fashion during a run of the program, prefereably without
having to close or open the file each time.

Now Linux will do this, so what I actually *need* is just the "C" 
interfaces to the standard C library.  The hard part is to integrate 
it with the readers and writers -- probably hard only if I'm 
actually going to figure out where it fits in the inheritance 
hierarchy of in/out things.  What surprises me is that the Modula 3 
distribution doesn't seem to have this already.

Just to get on with my project, I can probably make do with writing "C" 
interfaces to the raw Linux I'O system.

By the way, smarteiffel seems to be just as deficient.  It's as if 
language designers never encounter database implementers.
