non blocking named pipes

[Yves Serrano]

hi

I have a problem with named pipes....
I searched in the web, but don't found any working solution....

My Problem is that I have a pipe (/temp/pipe) where sometimes some data 
ist written into, but not very often.
I try to write a python script that opens the pipe and gets the data if 
its there. I no data is there the script
should not block, it should immediately exit without data.

How to do that?

I'm using python 2.2 on linux

regards yves
