Handle and kernel object

[xhsoldier]

Hanlde, always R class.
Kernel object, always D class.

I want to ask:
1. Does Handle belong to user space?
2. Does handle use fast or slow exec call to call the correspoding kernel object? In other words, handle use system call to interact with the kernel object?

you might want to read the internals book available on symbina press, it has quite good explanations on the kernel and other internal stuff.
