+ * Input Parameters:

+ *   event_id        - Event ID within the event base category
+ *   event_data      - Pointer to event data structure

+ *   ticks           - Number of ticks to wait (currently unused)

+ *   -1 on failure with following error conditions:
+ *      - Invalid event ID
+ *      - Memory allocation failure
+ *
+ * Assumptions/Limitations:
+ *   - Event data is copied into a new buffer, so the original can be freed
+ *   - Events are processed in FIFO order in the low priority work queue
+ *   - The function is thread-safe and can be called from interrupt context
