Module Name:
WinNtBlockIo.h
Abstract:
Produce block IO abstractions for real devices on your PC using Win32 APIs.
The configuration of what devices to mount or emulate comes from NT
environment variables. The variables must be visible to the Microsoft*
Developer Studio for them to work.
* Other names and brands may be claimed as the property of others.
