+Module Name:
+
+ UnixThunk.h
+
+Abstract:
+
+ This protocol allows an EFI driver in the Unix emulation environment
+ to make Posix calls.
+
+ NEVER make an Unix call directly, always make the call via this protocol.
+
+ There are no This pointers on the protocol member functions as they map
+ exactly into Unix system calls.
