hi guys!

i want to write a simulator in C, which outputs a string to a file or the memory. this simulator should be called every 0.1s and give a new output stream then.
a second program should read this stream in the memory and visualize it. Also this program should update the visualization every 0.1 sec.

The next step is to get the string stream from the usb board instead of the simulator. it should update the memory only if a new stream arrives at the usb eventdriven)

AS far as i know it til now the correct programm for such work is a daemon.
Is this correct? (first time that i do it)
how can two daemons interact (exchange data)?
Is there a howto available?

Please help me very fast!!!!!!!!!!!!!!!!!
