class ACE_Export ACE_Shared_Memory
  // = TITLE
  //     This base class adapts both System V shared memory and "BSD"
  //     mmap to a common API.
  //
  // = DESCRIPTION
  //     This is a very simple-minded wrapper, i.e., it really is only
  //     useful for allocating large contiguous chunks of shared
  //     memory.  For a much more sophisticated version, please check
  //     out the <ACE_Malloc> class.
