+/** @brief Encode PLDM PDR Repository Change eventData
+ * @param[in] event_data_format - Format of this event data (e.g.
+ * FORMAT_IS_PDR_HANDLES)
+ * @param[in] number_of_change_records - Number of changeRecords in this
+ * eventData
+ * @param[in] event_data_operations - Array of eventDataOperations
+ * (e.g. RECORDS_ADDED) for each changeRecord in this eventData. This array
+ * should contain number_of_change_records elements.
+ * @param[in] numbers_of_change_entries - Array of numbers of changeEntrys
+ * for each changeRecord in this eventData. This array should contain
+ * number_of_change_records elements.
+ * @param[in] change_entries - 2-dimensional array of arrays of changeEntrys,
+ * one array per changeRecord in this eventData. The toplevel array should
+ * contain number_of_change_records elements. Each subarray [i] should
+ * contain numbers_of_change_entries[i] elements.
+ * @param[in] event_data - The eventData will be encoded into this. This entire
+ * structure must be max_change_records_size long. It must be large enough
+ * to accomodate the data to be encoded. The caller is responsible for
+ * allocating and deallocating it, including the variable-size
+ * 'event_data.change_records' field. If this parameter is NULL,
+ * PLDM_SUCCESS will be returned and actual_change_records_size will be set
+ * to reflect the required size of the structure.
+ * @param[out] actual_change_records_size - The actual number of meaningful
+ * encoded bytes in event_data. The caller can over-allocate memory and use
+ * this output to determine the real size of the structure.
+ * @param[in] max_change_records_size - The size of event_data in bytes. If the
+ * encoded message would be larger than this value, an error is returned.
+ * @return pldm_completion_codes
+ * @note Caller is responsible for memory alloc and dealloc of param
+ * 'event_data.change_records'
