IOCTRL_INTERNAL_XXXX code
Posted by Liang Fu on June 2nd, 2005


Hi everyone,
I saw (with DbgPrint) an IOCTL_INTERNAL_XXXX with value 0xf0000 was passed
down the driver stack, I would like to know what it means. In which header
these code are defined?
Thanks,
Liang Fu

Have you looked at the online documentation? You should have installed it and
updated it with each new MSDN subscription drop. The current release is April
2005. Having that and looking for IOCTL_INTERNAL you would know that those
control codes are defined in a header file in the DDK.
