This structure is used for passing messages sent by notifications to subscriptions. It is the second parameter to the callback method specified in the ODPISubscrCreateParams structure.

Fields

event_type: ODPIEventType

Specifies the type of event that took place which generated the notification. It will be one of the values from the enumeration ODPIEventType.

db_name: *const c_char

Specifies the name of the database which generated the notification, as a byte string in the encoding used for CHAR data.

db_name_length: u32

Specifies the length of the db_name member, in bytes.

tables: *mut ODPISubscrMessageTable

Specifies a pointer to an array of ODPISubscrMessageTable structures representing the list of tables that were modified and generated this notification. This value will be NULL if the value of the event_type member is not equal to DPI_EVENT_OBJCHANGE.

num_tables: u32

Specifies the number of structures available in the tables member.

queries: *mut ODPISubscrMessageQuery

Specifies a pointer to an array of ODPISubscrMessageQuery structures representing the list of queries that were modified and generated this notification. This value will be NULL if the value of the event_type member is not equal to DPI_EVENT_QUERYCHANGE.

num_queries: u32

Specifies the number of structures available in the queries member.

error_info: *mut ODPIErrorInfo

Specifies a pointer to a ODPIErrorInfo structure. This value will be NULL if no error has taken place. If this value is not NULL the other members in this structure may not contain valid values.

tx_id: *const c_void

txid

tx_id_length: u32

txid length
