regarding privilege levels of pentium 4

[ranjith kumar]

 Hi,


  How can we tell at what privilege level a program is
running.
  Is it possible to run a program at privilege level
'zero' on a processor
like Pentium 4.

   Actually I want to disable interrupts while running
my program. This
can be done by "cli" instruction. Using "asm inline"
feature of GCC, we
can include assembly instructions  in programs of C,
C++...etc.

    But the problem is that "cli" instruction can be
executed only at
privilege level "zero".

Can anyone  help me.




Thanking you.
