What is cPlayer? As cTransfer implements both cReceiver and cTransfer

Typo? It should read "cTransfer implements both cReceiver and *cPlayer*":

Yes, a typo. I shouldn't write mails at that time :)

cPlayer sends data to the cDevice - what's not to understand here?

I thought about cDevice as input devices only. After reading PLUGINS.html and Udo's mail I understand that a cDevice also represents output devices (or both at the same time when using FF cards).

Use the source, Luke! ;-)

Although I'm doing software development for about 10 years I must admin that I very rarely came in contact with C++ code. I can read and write it, but it takes longer for me to get an overview as, let's say, in Java code. For example I had never before to deal with multiple inheritance (besides of Interfaces). But I'm doing my best :-)

You might also want to take a look at PLUGINS.html, especially the sections on "Players", "Receivers" and "Devices"

Thanks for the hint, I assumed that there must be further documentation, but somehow I missed this file.
