7.4 The seq_file is missing the behavior that occurs when it directly returns NULL after the start step.
Also, in the flowchart, the first decision where
return is NULL
isYes
points to nothing, which is not defined in ISO 5807.ISO 5807 section 10.3.1.2 states logic path of a decision, "Each exit from a symbol be accompanied by the appropriate condition values to show the logic path which it represents, so that the conditions and the associated references are identified."
The behavior of pointing to nothing does not have associated references and does not indicate the relation of this logic path.
