Any tutorials/articles on OS-ports ?

How do you initialize the io request (diskio)? It must be initialized properly. Usually this is made with CreateMsgPort + CreateIORequest (cleanup with DeleteIORequest, DeleteMsgPort).

Also, from look of the code, I think you should use DoIO (-456) instead of SendIO (-462). SendIO is asyncron, so you'd need to WaitIO manually to sync. DoIO does this for you automagic.

pieces of code that handle the (event) messages one is waiting for, so ones program (task) may "sleep" and "wake up" when the port is called (in order to free the OS from the task that would otherwise do nothing but wait for the message).

I am on the right path ?

Well, basically.

Here's some code using input.device .. there I set up the msgport and iorequest structures manually (and the structure fields are commented, too). It's far from proper explanation of things, however.

Developer CD 2.1 (which includes RKRM manuals) has nice docs about stuff, at least.

No. Use of includes makes the source code much more readable and easier to understand. The includes can be found from NDK3.9.lha.
