Request: port-closed? predicate #51

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
(port-closed? port) -> boolean

`port' can be any type of port.  Returns #t if the port is closed, #f if it
is open.

Ikarus and MzScheme have it and I need it for my libraries.

Thanks.

Thank you!
