Services of the Operating System  
Ok, first of all sorry for mi bad english; now this post it´s just because i have been reading about this amazing 
operating system and i would like to know a few things about it, as far as i understand other operating systems  are 
divided into  services, for example: I/O, Memory, Process, Files, Communication and Synchronisation, Protection and 
Security, etc.

So i would like to know how is divided the services of the kernel of this operating system. Sorry if this a dumb 
question, if it is just sorry.

The QNX Neutrino System Architecture guide should help you. Here's a
link to the latest version on our website:

Re: Services of the Operating System  
Ezgar,

That's a big question you are asking.  The short answer is that as much
as possible, we have nothing at all in the kernel with the exception of
what *must* be there (thread management and scheduling, message passing,
basic synchronization objects, etc) and we've move everything else out
to process level.  Some of the areas normally associated with the
operating system are implemented in a special process ("proc") that the
kernel is aware of (e.g. process management, some pieces of the file
system) while others are just normal processes, maybe with special
privileges (e.g. most device drivers).

I suggest you take a look at our system architecture documentation if
you want to study the details (you can find the latest released version
at
http://www.qnx.com/developers/docs/6.4.1/neutrino/sys_arch/about.html)

Re: Services of the Operating System  
Thanks about the link, Steve and Doug; it´s just that i want to know how everything works, i know it´s a kind of dumb 
way of thinking. Thank you again.
