Nit: Might want to say something like "|permission| is a set of ACCESS_MASK
flags; see the |grfAccessPermissions| field of
https://msdn.microsoft.com/en-us/library/windows/desktop/aa446627(v=vs.85).aspx
." or similar.

Does MSDN urls change? BTW, I'm negative about adding a specific URL because
none of them deliver the required information.

Adding a statement referring them to ACCESS_MARK and "file and directory access
right constants" may help though.
