Ubuntu, Kernel 2.6.22-14 and Python 2.5.1

I have a python program running capturing packets from LAN and writing it to a pipe. And a C++ program running reading from that pipe. Not i need to synchronize that. Everytime the python programm writes to the pipe it sends a signal to the c++ program that there is something in the pipe.

How do i do that? I'm googling for hours to find something. I found the kil() function but I'm still not sure how to do that...can anybody give...

Hey!

I'm new to python and I am trying to capture Radiotap Headers and to parse them to get the mac timestamp out.

So I found this for parsing radiotap headers:
http://www.wand.net.nz/~smr26/python/radiotap/radiotap.py

but before i can use that i need to capture the whole header in a string, and THATS my question right now: "How can I capture a radiotype header to a string?"
