Using the Returned Label String

The get_peer_label() function extracts the label from a remote host and returns that label as a string. The printing application, as is typical of label-aware applications, uses the label for the following purposes:

• To make sure that information associated with a label is clearly marked with the correct label. The banner and trailer pages, as well as the header and footer, are marked with the label of the document being printed.

• To validate that the label of a resource permits a given operation to be performed by another labeled resource. That is, the label of the requesting process permits this printer to accept a request from that requesting process. This permission is based on the range of labels that this printer is assigned.
