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.
