+ *                              for \p max_ops means functions will block for a
+ *                              lesser maximum amount of time. The functions

+ *                              means the whole operation will be done in one
+ *                              go, regardless of the number of ops required.
+ *
+ * \note                        If more ops are needed to complete a
+ *                              computation, #PSA_OPERATION_INCOMPLETE will be

+ *                              error code; or to call the relevant abort
+ *                              function if the answer is no longer required.
+ *
+ * \note                        The interpretation of \p max_ops is also

+ *                              system, this can indicate a hard deadline, as a
+ *                              real-time system needs a guarantee of not

+ * \warning                   This is a beta API, and thus subject to change at
+ *                            any point. It is not bound by the usual interface
+ *                            stability promises.
+ *
+ * \note                      This function is the only function that clears the
+ *                            number of ops completed as part of the operation.
+ *                            Please ensure you copy this value via

+ * \note                      Aborting an operation frees all associated
