CGAL 5.3 - Manual

Thread Local Storage

The header file <CGAL/tss.h> provides a macro CGAL_STATIC_THREAD_LOCAL_VARIABLE(TYPE,VAR,ARG1) that creates a thread local variable VAR of type TYPE, and passes ARG1 to the constructor. The variable is either threadlocal, or a boost::thread_specific_ptr, or just a local variable if CGAL_HAS_THREADS is not defined.


The header file <CGAL/mutex.h> provides a macro CGAL_MUTEX and a macro CGAL_SCOPED_LOCK(M) that is either a std::unique_lock<std::mutex> or a boost::mutex::scoped_lock.
