kernel vs user file name
Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance
I need to read a file in a kernel mode driver. The file name is passed from
a user mode application in the form of "C:\file" or \\Computer\Share\File.
Is there a standard kernel or user mode API, or some document describing the
proper algorithm to convert "C:\file" to "\??\C:\file" (or "\Device\...."),
and "\\Computer\Share\File" to "\Device\Lanman..." (or whatever), in order
to make a user mode file name usable in kernel mode?
Thank you.
