Structure Definitions

The structure definitions are provided in tables with the following information about each structure:

• Source — The name of the include file containing the C structure definition. The source files can be found in the ${IRIS_ROOT}/include directories.
• Byte — The byte offset of the structure element.

• Size — The data type of the element.

  For structures and spare space, the size in bytes is displayed here. Arrays are designated by a data type followed by a number in square brackets.

• Contents — A brief description of the structure element.

  Structure elements are identified with angle brackets such as <ymds_time>.

  <spare> indicates reserved space.
