Obtain a process label
Initialize labels
Find the greatest lower bound or the least upper bound between two labels
Compare labels for dominance and equality
Check and set label types
Convert labels to a readable format
Obtain information from the label_encodings file
Check that a sensitivity label is valid and within the system range
For a description of these APIs, see Chapter 2, Labels and Clearances.
