open-output-pipe[procedure] open-input-pipe cmdline [mode]
[procedure] open-output-pipe cmdline [mode]
Chicken: see also call-with-input-pipe, call-with-output-pipe,
with-input-from-pipe, with-output-to-pipe.
Some implementations allow to use "| cmdline" or "cmdline |" as
the filename in open-input-file and open-output-file
to achieve the same effects as these.
Gauche has open-input-process-port? and open-output-process-port?
which do the same thing.
