IOCTLs

If you ever need to look up an ioctl code by number, I wrote a little
tool to extract this information. The whole list from the 6000 WDK is here:

I used the C pre-processor to help make this list, which means I had to
make some choices. Ioctls that expired prior to Vista are not included.

just one gnit to pick … you misspelled WDK in the title.

Thanks Tim.

16 years of habits are hard to break. It will always be the DDK to me.

Hello, Tim,

I am just curious, where did you find FILE_DEVICE_AVIO? I have searched through WDK 6000 as well as the latest PSDK and could not find it. Your list has it as 0x99.

Thanks,

Well, he said sheepishly, I pulled 0x99 out of thin air because I
couldn’t find a proper definition…

I assume the three ioctls that use it are internal to the kernel and
should have been #ifdef-ed out.
