Next: Accessing the data stream, Previous: Introduction, Up: Top
Before accessing the data, it is important to understand how the data stream is organized and presented to the program.
The data stream consists of a single header packet, followed by multiple data packets. The header packet is split into three sections:
The data are organized into fields, and are identified by names. Data are present in the stream in binary form, and consist of scalars or tensors composed of intrinsic data types. Synthesized data types (structures or records) are not currently supported. The data types that are available (for both header and data packet data) are listed in Intrinsic Data Types.
