Basic Data Structures
Once your connection is alive and active, any requests made to the server for registered properties and services are automatically forwarded to your application, and the appropriate callback function is called. To push properties to the ThingWorx Platform, you can use helper functions to execute a service on another entity in the system or to trigger an event on the platform. These helper functions are described in the section, SDK Application-Initiated Interaction.
Data points in the C SDK are represented in the form of a twPrimitive structure. Collections of data values are represented in the form of a twInfoTable structure. Each of these structures is defined next, and the API functions to access them are found in src/messaging/twBaseTypes.h and twInfoTable.h, respectively.
