46 -  **Discrete:** The function returns success if the given index value
47    (zero-based) is valid. The application should increase the index by
53 -  **Step-wise:** The function returns success if the given index value
54    is zero and ``EINVAL`` for any other index value. The
59 -  **Continuous:** This is a special case of the step-wise type above.
60    The function returns success if the given index value is zero and
66 When the application calls the function with index zero, it must check
98 application should zero out all members except for the *IN* fields.
