(Note that this specifically holds +for <a +href="http://www.lispworks.com/documentation/lw50/LWRM/html/lwref-91.htm">bivalent +streams</a> like socket streams.) + +A flexi stream behaves like an ordinary Lisp stream. It is an input +stream if the underlying binary stream is an input stream, and it is +an output stream when the underlying binary stream is an output +stream. You can write characters as well +as <a href="#octet">octets</a> to an output flexi stream and similarly +you can read characters and octets from an input flexi stream. + +A flexi stream always has an <a href="#external-formats">external +format</a> associated with it which is deployed whenever you read +characters from the stream or write characters to it. You +can <a href="#flexi-stream-external-format">change</a> the external +format while you use the stream. + +Once you're using a flexi stream you should not read from or +write to the underlying stream directly anymore. + +If +you <a +href="http://www.lispworks.com/documentation/HyperSpec/Body/f_close.htm">close</a> +a flexi stream, the underlying stream will also be closed. However, it +also suffices to close the underlying stream directly should you not +want to use the flexi stream anymore. So, the following usage +(where <code>IN</code> is implicitly closed at the end) is OK: +<pre> +(with-open-file (in "/foo/bar/baz.txt") + (let ((flexi (<a href="#make-flexi-stream" class=noborder>make-flexi-stream</a> in <a href="#external-formats" class=noborder>:external-format</a> :hebrew))) + (read-line flexi))) +</pre> + +Output flexi streams will try to keep track of +the <a +href="http://www.lispworks.com/documentation/lw50/LWRM/html/lwref-591.htm">column</a> +they're in but you can also <a href="#flexi-stream-column">set</a> the +column directly. This value will be incremented by one for each +character written to the stream and it will be set to <code>0</code> +if you send a <code>#\Newline</code> character. The column will be +set to <code>NIL</code> if an <a href="#octet"><code>OCTET</code></a> +is sent to the stream. Once the column is <code>NIL</code> it'll stay +like that unless it is explicitly set to another value. + +Input flexi streams keep track of +their <a href="#flexi-stream-position">position</a> within the stream. +This value is incremented by one for +each <a href="#octet"><code>OCTET</code></a> read from the stream, and +it is incremented by the number of octets actually read for each +character read from the stream. So, if the encoding is UTF-8, reading +the character <code>#\ä</code> (a-umlaut) will advance the position by two. +If the encoding is UTF-32 and the end-of-line style +is <code>:CRLF</code>, reading a <code>#\Newline</code> will advance +the position by eight. + +You can also set the <a href="#flexi-stream-bound">bound</a> of an +input flexi stream. Initially it is <code>NIL</code>, but when it's +an integer and the +stream's <a href="#flexi-stream-position">position</a> has gone beyond +this bound, the stream will behave as if no more input is available. + +Caveat: You can +only <a +href="http://www.lispworks.com/documentation/HyperSpec/Body/f_unrd_c.htm">unread</a> +a character from a flexi stream if you haven't changed the external format after you read it. + +Caveat: The underlying stream should either be a <a href="http://www.lispworks.com/documentation/HyperSpec/Body/26_glo_b.htm#binary">binary stream</a> (i.e. have an element type that is a subtype of integer) or it should explicitly use an <a href="http://www.lispworks.com/documentation/lw50/LWUG/html/lwuser-360.htm">external format</a> with <code>:LF</code> as its end-of-line style.

aus unruhigen Tr�umen erwachte, fand er sich in seinem Bett zu einem ungeheueren Ungeziefer verwandelt. Er lag auf seinem panzerartig harten R�cken und sah, wenn er den Kopf ein wenig hob, seinen gew�lbten, braunen, von bogenf�rmigen Versteifungen geteilten Bauch, auf dessen H�he sich die Bettdecke, zum g�nzlichen Niedergleiten bereit, kaum noch erhalten konnte. Seine vielen, im Vergleich zu seinem sonstigen Umfang kl�glich d�nnen Beine flimmerten ihm hilflos vor den Augen. �Was ist mit mir geschehen?�, dachte er. Es war kein Traum. Sein Zimmer, ein richtiges, nur etwas zu kleines Menschenzimmer, lag ruhig zwischen den vier wohlbekannten W�nden. �ber dem Tisch, auf dem eine auseinandergepackte Musterkollektion von Tuchwaren ausgebreitet war - Samsa war Reisender - hing das Bild, das er vor kurzem aus einer illustrierten Zeitschrift ausgeschnitten und in einem h�bschen, vergoldeten Rahmen untergebracht hatte. Es stellte eine Dame dar, die mit einem Pelzhut und einer Pelzboa versehen, aufrecht dasa� und einen schweren Pelzmuff, in dem ihr ganzer Unterarm verschwunden war, dem Beschauer entgegenhob. Gregors Blick richtete sich dann zum Fenster, und das tr�be Wetter - man h�rte Regentropfen auf das Fensterblech aufschlagen - machte ihn ganz melancholisch. �Wie w�re es, wenn ich noch ein wenig weiterschliefe und alle Narrheiten verg��e�, dachte er, aber das war g�nzlich undurchf�hrbar, denn er war gew�hnt, auf der rechten Seite zu schlafen, konnte sich aber in seinem gegenw�rtigen Zustand nicht in diese Lage bringen. Mit welcher Kraft er sich auch auf die rechte Seite warf, immer wieder schaukelte er in die R�ckenlage zur�ck. Er versuchte es wohl hundertmal, schlo� die Augen, um die zappelnden Beine nicht sehen zu m�ssen, und lie� erst ab, als er in der Seite einen noch nie gef�hlten, leichten, dumpfen Schmerz zu f�hlen begann. �Ach Gott�, dachte er, �was f�r einen anstrengenden Beruf habe ich gew�hlt! Tag aus, Tag ein auf der Reise. Die gesch�ftlichen Aufregungen sind viel gr��er, als im eigentlichen Gesch�ft zu Hause, und au�erdem ist mir noch diese Plage des Reisens auferlegt, die Sorgen um die Zuganschl�sse, das unregelm��ige, schlechte Essen, ein immer wechselnder, nie andauernder, nie herzlich werdender menschlicher Verkehr. Der Teufel soll das alles holen!� Er f�hlte ein leichtes Jucken oben auf dem Bauch; schob sich auf dem R�cken langsam n�her zum Bettpfosten, um den Kopf besser heben zu k�nnen; fand die juckende Stelle, die mit lauter kleinen wei�en P�nktchen besetzt war, die er nicht zu beurteilen verstand; und wollte mit einem Bein die Stelle betasten, zog es aber gleich zur�ck, denn bei der Ber�hrung umwehten ihn K�lteschauer. Er glitt wieder in seine fr�here Lage zur�ck. �Dies fr�hzeitige Aufstehen�, dachte er, �macht einen ganz bl�dsinnig. Der Mensch mu� seinen Schlaf haben. Andere Reisende leben wie Haremsfrauen.
