One of the new simple-stream subclasses in Allegro CL 6.0. Equivalent
to the Gray stream file-stream and a subclass of both file-simple-stream and
direct-simple-stream. Similar to
file-simple-stream but
opening a file mapped allows for much faster access to the file, with
much less kernel overhead. Note: most operating systems do not allow
the automatic extension of mapped files, so this class does not allow
the extending operation either. Writes beyond the end of the file may
cause an error. A mapped file must be opened with :direction :io and
:mapped t specified to open..
See streams.htm for general information on simple-streams in Allegro CL.
The documentation is described in introduction.htm and the index is in index.htm.
