Label Range APIs

A label range is used to set limits on the following:

• The labels at which hosts can send and receive information

• The labels at which processes acting on behalf of users and roles can work on the system

• The labels at which users can allocate devices

  This use of a label range restricts the labels at which files can be written to storage media on these devices.

Label ranges are assigned administratively. Label ranges can apply to users, roles, hosts, zones, network interfaces, printers, and other objects.

You can use the following methods to obtain information about label ranges:

• getuserrange() obtains the user's label range.

• getdevicerange() obtains the label range of a device.

• tninfo -t template-name shows the label range of a template that is associated with a network interface.

For a description of these APIs, see Chapter 2, Labels and Clearances.
