+Module Name:

+
+Abstract:
+
+ Since the SEC is the only windows program in our emulation we
+ must use a Tiano mechanism to export Win32 APIs to other modules.
+ This is the role of the EFI_WIN_NT_THUNK_PROTOCOL.
+
+ The mWinNtThunkTable exists so that a change to EFI_WIN_NT_THUNK_PROTOCOL
+ will cause an error in initializing the array if all the member functions
+ are not added. It looks like adding a element to end and not initializing
+ it may cause the table to be initaliized with the members at the end being
+ set to zero. This is bad as jumping to zero will case the NT32 to crash.
+
+ All the member functions in mWinNtThunkTable are Win32
+ API calls, so please reference Microsoft documentation.
+
+
+ gWinNt is a a public exported global that contains the initialized
+ data.
