[gambit-list] Something like ##device-port-eof? available?

Dear Marc,

How do I know if a device port reached EOF?

Is there a flag internally in Gambit somewhere I suppose there is a flag internally somewhere in Gambit that keeps track of this. |wait-for-input|just returns immediately. Of course I could do something like (read-subu8vector v 0 1 port 0) though in this particular application I'd much prefer to only do the socket reading and writing completely outside the scope of Gambit's IO system.

If it's not in Gambit then please just say so, there's always another implementation path, though I'd appreciate not to go into higher complexity than needed.

Thanks!

(define (port-wait-for-input port) (##wait-for-io! (device-port-rdevice-condvar port) (port-rtimeout port)))
