Hello,
I am developing a filter graphics kext that will call the
original graphics kext's functions.
Is it possible to call a function of already loaded graphics
kext( eg call alloc_texture function of ATIRadeon8500.kext ) from my
filter kext .
I dont have the source code for ATIRadeon8500 so no header file
is availablle with us , only information that is availabe the symbols
(eg ATIRadeon8500::allocate_Texture(),
ATIRadeon8500::alloc_and_load_texture) .
Now I want to call these functions from my graphics kext .
What I am trying to do is :
In Dependencies I have given ATIRadeon8500
I am inheriting my class from ATIRadeon8500 which is failing ,
and that should be correct as how my application will find the class
ATIRadeon8500 . eg class com_abc_driver_pqr : public ATIRadeon8500
->error : class ATIRadeon8500 undeclared .
The basic purpose is to inherit my class from ATIRadeon8500 , so as
to call the functions of ATIRadeon from my own kext .
In the example source code IOKitWithLibrary , they are preparing
their own Library kext and I dont have that priviledge here.
Is there a way to achive it.
Thanking You
