get-output-stream-string string-output-stream => string

Arguments and Values:

string-output-stream---a stream.

string---a string.


Returns a string containing, in order, all the characters that have been output to string-output-stream. This operation clears any characters on string-output-stream, so the string contains only those characters which have been output since the last call to get-output-stream-string or since the creation of the string-output-stream, whichever occurred most recently.


 (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.
