This works identical to pthread_once(3) with the additional property that it is safe for routines in libc to use in both single-threaded and multi-threaded processes. Multi-threaded processes use the pthread_once() implementation from the threading library while single-threaded processes use a simplified "stub" version internal to libc. END
