Detailed Description

This base class adapts both System V shared memory and "BSD" mmap to a common API.

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.
