      Miscellaneous API
      1. Anchor
        1080623
        1080623
        Objects in µC/OS-III are named when they are created and these functions are not required in µC/OS-III.
      2. Anchor
        1080624
        1080624
        The implementation of the multi-pend functionality is changed from µC/OS-II. However, the purpose of multi-pend is the same, to allow a task to pend (or wait) on multiple objects. In µC/OS-III, however, it is possible to only multi-pend on semaphores and message queues and not event flags and mutexes.
      3. Anchor
        1182571
        1182571
        µC/OS-III returns an error code for this function. Initialization is successful if OS_ERR_NONE is received from OSInit(). In µC/OS-II, there is no way of detecting an error in the configuration that caused OSInit() to fail.
      4. Anchor
        1080626
        1080626
        An error code is returned in µC/OS-III for this function.
      5. Anchor
        1080627
        1080627
        Enable or disable µC/OS-III’s round-robin scheduling at run time, as well as change the default time quanta.
      6. Anchor
        1080628
        1080628
        A task that completes its work before its time quanta expires may yield the CPU to another task at the same priority.
      7. Anchor
        1080629
        1080629
        An error code is returned in µC/OS-III for this function.
      8. Anchor
        1080630
        1080630
        Note the change in name for the function that computes the “capacity” of the CPU for the purpose of computing CPU usage at run-time.
      9. Anchor
        1080631
        1080631
        An error code is returned in µC/OS-III for this function.
