A stream is a Lisp object which is either a data sink (an output stream) or a data source (an input stream). All streams produce or consume sequences of 8-bit characters.
Streams are very flexible, functions using streams for their input and
output do not need to know the type of stream being accessed. For
example the Lisp reader (the
read function) takes an input
stream as its sole argument, it then reads characters from this stream
until it has parsed a whole object. This stream could be a file, a
function, or even a string; the
read function does not need to
Return true if arg is a stream.
Return true if arg is an input stream.
Return true if arg is an output stream.
