Examples:
(setq a-stream (make-string-output-stream)
a-string "abcdefghijklm") => "abcdefghijklm"
(write-string a-string a-stream) => "abcdefghijklm"
(get-output-stream-string a-stream) => "abcdefghijklm"
(get-output-stream-string a-stream) => ""
Side Effects:
The string-output-stream is cleared.
Affected By: None.
Exceptional Situations:
The consequences are undefined if stream-output-string is closed.
The consequences are undefined if string-output-stream is a stream that was not produced by make-string-output-stream. The consequences are undefined if string-output-stream was created implicitly by with-output-to-string or format.
