Re: implementing bash's magic

[Roland McGrath]

The /dev/fd cases use magic with libc support old because that is the only
sensical way to implement them.  For other features you can just use normal
translators that do the work themselves.  i.e., to return a connected
socket from open, they can get an io_restrict'd port to /servers/socket/N
and call socket_create, socket_connect, etc., and return the port.
