I don't understand -- what does the $(VAR) refer to? Which process's environment is used for $(VAR)? Or is VAR not an environmental variable?
The process making the call, of course.
If it is an environmental variable, wouldn't the environment have to be passed around?
Well, I don't recall whether this was in user space or not (it has been a while). It may well be that the kernel simply maintained a pointer to the user environment, and so had it available for reference when the kernel mapped a name into an object.
