Thanks, this is what really helped. I had been playing with QueryDosDevice but the docs on MSDN were not the best - the sample code cleared up everything.<br />

Do you happen to know how Internal NT Device Names are assigned?<br />
<br />
I'm wondering in what cases the \Device\HarddriveVolume2 would change... for example, whether it would change if another HDD were added, if Volume1 were deleted then perhaps Volume2 would change to be Volume1, etc etc.

AFAIK the object manager assigns these upon boot. You can be sure that they (except for removable devices) do not change at runtime.

I'm trying to find an API to normalize a path passed as a parameter, for example:<br />
<br />
c:\windows\system32\driver<wbr />.sys --&gt; \Device\HarddiskVolume2\wi<wbr />ndows\syst<wbr />em32\drive<wbr />r.sys<br />
\\server\path\file.ext --&gt; \Device\LanmanRedirector\s<wbr />erver\path<wbr />\file.ext<br />
<br />
Any pointers to a Win32 API to accomplish this would be very helpful.

c:\windows\system32\driver.sys --> \Device\HarddiskVolume2\windows\system32\driver.sys
\\server\path\file.ext --> \Device\LanmanRedirector\server\path\file.ext

Normalize path name API

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
