- What is the mechanism for inter-subsystem communication ?
- Can it be anything other than shared memory ? It seems not since each
- subsystem has its' own view of what a process is and does not understand
- a process in another subsystem, except perhaps at a level lower than
- the subsystem level ie probably something at the kernel level.
- Can subsystems "sneak under the covers" and communicate with other subsystems
- through the kernel ?
-
- I'm just guessing here but I don't see any obvious other way than
- shared memory. Even then can subsystems exchange handles to something
- like "system global" shared memory ?
-
- Since the current doc set doesn't contain any info on the POSIX subsystem
- for NT, it's not clear what the interfaces are between subsystems ?
- Any one willing to clarify ?

- Unrelated question :-
-
- Can POSIX apps using sockets make calls to winsock or does a separate
- sockets implementation have to be written for a POSIX sockets app ?
