It has to match signature that "pthread_create" expects so it has to be
static method or generic function and extern "C" is not necessary. For
example:

class foo {
   void thread_function();
public:
   static void *static_func( void * ptr) { reinterpret_cast<foo *>( ptr
)->thread_function(); }
};

....
foo *test;
pthread_create( thread, attr, foo::thread_func, test );
....
