Connecting to the IO stream

I am trying to get my native object to call the code I created for Operating Systems. The code reads input from a PS3 Sixaxis controller. This would show how I can communicate with low level code through my native object.

The problem is that:
1) I'm not sure where to put that .c file.
1.1) I could just dump it in the js directory but that doesn't seem right.
2) I'm not sure where in the make file to add it or which make file to add it to
3) The code prints to standard out. Would I need to have a shell open? How would I see the output?
4) Making small changes then recompiling is insanely time consuming because the compile time is about 15min.

I'm trying to figure this out but it may take a while.
