library calls which create threads in RT space also run in RT space
which is kernel space. So there is no reference to user space here.
Whereas user space applications run in the context of the respective
applications' process context which is user space. Check with "Frank"
example.

Subject: [rtl] doubt regd library calls
hi everybody,
I have some doubt about library calls. I read in OS
concepts that kernel space program should not make
references to user space processes. Am i right ?
In RTLniux, every realtime module runs in Kernel
space. And we are making library calls to create
threads which runs in User space. but according to OS
concepts process running in Kernel space should not
refer User space..
Please clarify my doubt..
Regards
Venkat
