From an OS standpoint, it is not a Unix clone (in that way that Linux is).  On the other hand, the concepts embodied in Unix and the Unix API's have become so ingrained into the OS and programming community, that it is hard to imagine any OS today that doesn't look a whole lot like Unix in many ways.

I'm going to have to answer this in several parts....
1.  The right to use the "Unix" trademark implies that the system meets the Unix98 specification maintained by the Open Group (www.opengroup.org).  The complete specification is available from http://www.opengroup.org/online-pubs?DOC=007908799
2.  The Unix98 specification is largely based on the IEEE POSIX standard for operating systems.  I don't think this is freely available on line, but you can check the IEEE web site (www.ieee.org).
3.  Many suppliers of Unix and Unix-like operating systems also provide their own documentation sites.  Some examples are docs.hp.com, www.freebsd.org, docs.sun.com, uw7doc.sco.com,  and www.linuxdoc.org.
4.  For the most part, these documents all address a C based API, and are not specific to C++.  However, note that a) any C API can be called from C++ and b) the standard C++ libraries for IO, memory management, process management, etc. are already heavily Unix-centric (as Bjarne was from the Unix group at Bell Labs).
