As Ken Dickey said: "It would be useful to test an output-port to see if get-output-string can be applied."
get-output-string
That procedure is defined in src/Lib/Common/stringio.sch but isn't available at the R5RS top level.
This temporary workaround is extremely representation-dependent and might break in future versions of Larceny, but it works in v0.99:
(import (primitives vector-like-ref)) (define port.iodata 7) ; ouch (define (string-output-port? port) (and (output-port? port) (let ((d (vector-like-ref port port.iodata))) (and (vector? d) (> (vector-length d) 0) (eq? (vector-ref d 0) 'string-output-port)))))
