get-output-stream-string string-output-stream => string
Arguments and Values:
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.
