C++ threads are always a wrapper around an underlying library.  So if 
you are using C++ on Linux, the C++ threads /are/ pthreads.  These are 
the points I can think of for preferring C++ threads:

+ You have a nice class/template library with C++ threads, instead of a 
C function interface.

+ You have have RAII classes for locks and other synchronisation objects.

+ You have consistency with other C++ thread systems.

+ Your compiler may understand that your code is threaded.

- You need at least C++11 (but that has huge advantages anyway, compared 
to older C++).

- It is marginally more fiddly if you need the underlying thread details 
for features not supported by the C++ thread library.
