IOCTL function numbers

NTFSD
1

Hello experts:

Is there any documentation of the Device Ioctl functions for the disk
drivers? I am getting these values for the IOCTL function numbers:

0x66001b 0x7c084 0x74080 0x7c088 0x32c000
0x41020 0x41018

Can anyone please tell me where I can find out what this IOCTLs are and what
are their parameter definitions?

Thanks

Basudeb

check out the IOCTL program on www.osr.com. That will help you dissect the
function codes. THen you can search for the function numbers and device
types in the .h files.
