fork pipe dup2 exec

[Tobias Reithmaier]

Hello,
is there a way to program a Inter Process Communication (IPC) in guile like you 
do it with the Linux-Libc-API with the combo fork, pipe, dup2 and exec?If you 
use the popen-module it's not the same because you have to wait until the 
program has finished.But there are use-cases in that the program doesn't 
finish. e.g. a server which outputs data every minute.
So can i use the popen-module to control such a server with pipes?Or is there 
another way?
greetings-tobi
