Can anyone give me a hint how to start finding out about XPCOM services and parameters? The only thing I know is the reference at xulplanet.com, but this doesnt tell me what exactly each method does, nor what the meaning of each parameter is (only its type).
So when I want to write some javascript code that needs to create files, get the list of files in a directory and so on, where do I find out how to do that with XPCOM? Of course I would also be interested in error conditions ... Johann
