Here are the data structures with brief descriptions:
| C_ds5_namespace_s | Definition of the interface that you should implement if you require custom subject matching logic |
| C_ds_data | A data update object |
| C_ds_field | A field within a data update |
| Capplication_t | Structure containing application licencing information |
| Casset_class_t | Structure containing asset class information |
| Cds5_connectionlistener_t | Implement this interface to receive connection status information when using the DSv5 API |
| Cds5_dataprovider_t | Interface that must be implemented in order to receive subscirption request and subscription discard events for DataSource subjects from connected DataSource peers. the implementation sends data to connected peers in response to subscription requests |
| Cds5_subscriptionlistener_t | An implementation of this interface allows applications to receive events raised for a ds5_subscription_t |
| Cds_arguments_t | Structure defining the arguments for Monitoring methods |
| Cds_array_t | The container object for monitoring array types |
| Cds_config_enum_t | Enumerated types structure |
| Cds_init_t | Defines the DataSource initialisation object |
| Cds_monauth_t | Monitoring credentials object |
| Cds_monitor_t | The container object for all monitoring values |
| Csigkey_t | Configuration structure used to hold keyfile information |
