Re: Joining two pipes

[Volodymyr Bezobiuk <dedoogun@...>]

Do you need the way to write to another process' stdout and read from that process' stdin ?

If this is the case you may need mkfifo (available in luaposix).

Here's the bash snippet to solve this issue, it can be adopted:

mkfifo /tmp/fifo

process1 < /tmp/fifo | process2 > /tmp/fifo

rm /tmp/fifo

io.popen can either pipe to or pipe from a program. That's
because the C library routine can only do one of the two.

Now suppose a certain program writes unbuffered output.
Is there any way (coroutine, temporary file, whatever) to
read whatever output has just been written after providing
some input?
