WindowsFileProtection.cpp
|
|
|
|
Abstract:
|
|
|
|
This AppVerifier shim hooks the file I/O APIs that could
|
|
potentially change a file under Windows File Protection.
|
|
|
|
When one of the files is accessed or modified, an event
|
|
is written to the log.
|
|
|
|
Notes:
|
|
|
|
This is a general purpose shim.
|
|
|
|
History:
|
|
|
|
06/25/2001 rparsons Created
|
|
|
|
11/26/2001 rparsons Remove unused local variables.
|
|
Make SHFileOperation more efficent.
