RE: Can I take the address of a function argument?
The first function takes a pointer - so you already got the address of the buffer where you are expected to store the answer.
The second function takes an int - that is a local copy so you may take the address of this local variable Arg but can't return…
Declaring local variable causes L15 warnings, but only on optimization level 9

Sorry, but I couldn't find the driver.
But I did have a kit with 27 viruses I did send. It is quite creative, with permutating, self-modifying code, so it just might support transposing itself for use as a driver. I'm not sure if your virus scanner…

RE: volatile int typecast return value. Could this make problem?
