- * Name: pthread_once
- *
- * Description:
- *   The  first call to pthread_once() by any thread with a given once_control,
- *   will call the init_routine with no arguments. Subsequent calls to
- *   pthread_once() with the same once_control will have no effect.  On return
- *   from pthread_once(), init_routine will have completed.
- *
- * Parameters:
- *   once_control - Determines if init_routine should be called.  once_control
- *      should be declared and intialized as follows:
- *
- *        pthread_once_t once_control = PTHREAD_ONCE_INIT;
- *
- *       PTHREAD_ONCE_INIT is defined in pthread.h
- *   init_routine - The initialization routine that will be called once.
- *
- * Return Value:
- *   0 (OK) on success or EINVAL if either once_control or init_routine are
- *   invalid
- *
- * Assumptions:
- *
