[ros-dev] Subsystems, how to write one

[crashfourit]

What are the relevent ReactOS API calls for building a dynamicly 
loadable subsystem?
I'm asking this because I can't find the API documentation on the 
website. (I looks more like the documentation is not yet completed.)

Other questions relevent to this:
How do I register a new executible file format? I.E. coff.
How do I register a new interrupt vector(s).
What are the API to control v86 prosses?

If y'all want to know what subsystem I want to write, it is DOS. This is 
because I'm more familar with programing in DOS.
