Module Name:
|
|
|
|
UnixBlockIo.h
|
|
|
|
Abstract:
|
|
|
|
Produce block IO abstractions for real devices on your PC using Posix APIs.
|
|
The configuration of what devices to mount or emulate comes from UNIX
|
|
environment variables. The variables must be visible to the Microsoft*
|
|
Developer Studio for them to work.
|
