- Subject: fd number to io object?
- From: duck <duck@...>

Forgive my ignorance (can't find an answer by searching), but can I map a
specific file descriptor onto an io object?
Socat, a handy network utility program, lets you make bidirectional
pipelines of sub-processes in which fd 0 and 1 are the input from, and
output back to, the command to your left in the pipeline, and fd 3 and 4
are the input back from, and output onwards to, the command to your right
in the pipeline.
Fds 0 and 1 are obviously just io.stdin and io.stderr. Can the same
arrangement be made to map fds 3 and 4 onto io objects?
