IORegistry access from user space



Hi,

I have the IOKit driver.
I want to do 2 things.
1. I want to write an application who takes input as Base_class name,
and gives list of driver objects derived from this base class in
io_iterator_t.
How can I do this? Is there any API available.


2. My IOKit driver IORegistry contains one OSDictionary property and other
OSString objects.
i.e. I want to read those properties from user space.
How can I read value of that OSString object from user space?
getObject() copyProperty() are some methods available in the IOKit, but what
is equivalent of it in user space?

Regards,
Parav Pandit
