This looks like the NT kernel coding style, especially with the pointless typedefs for things like PVOID and the PascalCased function names with prefixes like `IopPerformIoOperation`. I looked up the Minoca founders on Linked In and, behold, they both worked as engineers on the Windows NT team. :)
NT source code typically (and I say typically, because it's a mish-mash of tens of thousands of people's work over 35 years of development) has local variable names in first-letter-lower camel case. If these guys worked on Windows, it's kind of surprising they didn't follow that convention.
