// There are several possibilities for the exit handlers.
// To use the default implementation (which uses atexit()), nothing special has to be done.
//
// To work around problems with atexit() being used in a dll you may #define STXXL_NON_DEFAULT_EXIT_HANDLER at library compilation time.
// In this case the library/application should call stxxl::run_exit_handlers() during shutdown.
//
// To provide your own exit handler implementation, #define STXXL_EXTERNAL_EXIT_HANDLER and implement
// stxxl::register_exit_handler(void (*)(void)) and stxxl::run_exit_handlers() in your application.
