Header Section

This section contains the common SMF record header fields and the triplet fields (offset/length/number), if applicable, that locate the other sections on the record.

This triplet information should be checked before accessing a section of the record. All three filed being non-zero mean that the section does not exist on the record. The ‘number’ triplet filed is the primary indication of the existence of the field.
