Can we say that while programming, showing something on output, adding values etc., we always interact with system? I mean whether every function in app ends up(finally) in kernel.
I don’t know if this approach varies from OS to OS so I mean Windows.
I appreciate Your response, and I am sorry for my English.
You always interact with the system in that the CPU (or some other processor like a GPU) has to execute your code.
Not every instruction executed by the CPU will involve a kernel-mode operation, though.
