Getting the original stdin, stdout, and stderr is unsafe from Racket's perspective (which wants to allow a program to control the ports that a sandboxed program can reach, for example). You could use the FFI to get those ports, though.That's more than I'd want to get involved with in this case, for what is basically a quick utility program. [...]
Hello,perhaps it would be an option to open /dev/tty in order to obtain a fresh handle to the current controlling terminal that could then be passed on to an external process' standard input, output and/or error.
Of course that solution is only portable to *nix systems. Ciao, Thomas -- When C++ is your hammer, every problem looks like your thumb.
