-/*++ @file
- Since the SEC is the only program in our emulation we
- must use a UEFI/PI mechanism to export APIs to other modules.
- This is the role of the EFI_EMU_THUNK_PROTOCOL.
-
- The mUnixThunkTable exists so that a change to EFI_EMU_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 crash.
