C. New and Changed Features

This section describes new and changed features for this release of the OpenMP API. For details, see the OpenMP API User's Guide at http://docs.sun.com/doc/819-5270.

Changes introduced in the Sun Studio 12 release of OpenMP:

1. OpenMP 2.5
   The OpenMP implementation has been upgraded to the published 2.5 specification. See the OpenMP website http://www.openmp.org/ for details.
      
   
2. C++ Autoscoping
   Automatic scoping of variables is now enabled for C++ programs as well as C and Fortran 95. Autoscoping is described in Chapter 3 of the OpenMP User's Guide.
   
   For C and C++, autoscoping is available for basic data types: integer, floating point, and pointers. The syntax of the declaration clause is similar to Fortran 95:  __auto and default(__auto).
