# 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 `thread_local`, or just a local variable if `CGAL_HAS_THREADS` is not defined.

# Mutex

The header file `<CGAL/mutex.h>` provides a macro `CGAL_MUTEX` equivalent to `std::mutex` and a macro `CGAL_SCOPED_LOCK(M)` that is a `std::unique_lock<std::mutex>`.
