DNS Structured Tokens The DNS programmatic interface uses structured tokens almost exclusively, even in

cases where the structure contains only one field. (A notable exception is that all

tokens appearing in error responses are simple tokens; these are described earlier in

this section.)

Token Structure Format

Most structured tokens have names with the following format:

ZDNS-MAP-

ccccc

ttttt

[ -

var

]

In this format,

ccccc

is an abbreviation of the command number listed in Table 4-8,

and

ttttt

is an abbreviation of the object type as listed in the same table.

Note that RESTORE uses the same parameters as COPY and STATUS uses the same

parameters as INFO; thus, these pairs share command abbreviations. LISTOPENS

uses INFO parameters, so there are no LISTOPEN definitions; since this command

applies only to ZDNS-OBJ-PROC, the parameter is ZDNS-MAP-INFO-PROC-P and

the response is ZDNS-CMD-LISTO-PROC-P.

In some cases of object types, ZDNS-OBJ-ALIAS, ZDNS-OBJ-COMP, ZDNS-OBJ-

DOM, and ZDNS-OBJ-GROUP use the same parameter and response tokens. In these

instances, the abbreviation DNSOBJ is used (as in, for example, ZDNS-MAP-DEL-

DNSOBJ).

ZDNS-OBJ-ATYPE and ZDNS-OBJ-CTYPE also share tokens in some cases. In these

instances, the abbreviation DNSTYPE is used (as in, for example, ZDNS-MAP-DEL-

DNSTYPE).
