Control-and-Inquiry
Interface
Management applications interact with DNS by opening a name manager process and
sending requests to that manager. The name manager acts upon each request and
returns a response to the requestor. The management application’s requests are
commands formatted in SPI buffers; it receives responses from DNS in the same
format. The commands alter or delete object names in a DNS database, or make
inquiries, such as what names are in a group. Figure 1-3 illustrates the control-and-
inquiry interface to DNS for commands and responses.
