[Chicken-users] Is it possible to emulate a port in chicken?

[Julian Morrison]

By emulating a port, I mean: creating a "fake" port object which hands 
off reads and writes to callback functions. That would allow new sorts 
of ports to be defined in libraries eg: TLS port. At the moment I can't 
see any way to do this. Is there one? I assume worst case I could use 
FFI to muck about with chicken's internal port representation.

Also, suggestion: add a library call that reverses the posix library's 
(port->fileno) to allow a FD to be wrapped in a port. This is useful eg: 
in circumstances where a FD is inherited from the parent process, such 
as in programs called by inetd.
