Dave Brown says

<<Ok, so I am reading the file data into a stream element buffer
(Stream_Element_Array).  My file, however, really consists of some
small objects (16 bit signed integers).  What is the "proper" way to
get these integers out of this buffer?  I want there to be as little
copying of these numbers as possible.  Here are some solutions I've
come up with:>>

Well first, as you go on to mention, you may well find that it is
efficient enough to use the stream attributes directly in the first
place.

If not, I would still use Stream_Attributes as the mechanism, but
write your own to access the buffer efficiently.
