SYS
is similarly, a variant used to indicate that the command pertains to a system in a
domain, rather than to the domain itself.
Token Definition Format
The DDL definition for a structured token has a name of the form:
ZDNS-DDL-ccccc-ttttt [ -var ]
In this syntax, ccccc, ttttt, and var are the same as described under “Token Structure
Format.”
In the remainder of this section, where a structured token is referenced, the -MAP-
form of the name is used. When the DDL definition is referenced, the -DDL- form of
the name is used.
Appendix A provides a complete list of all DNS token codes, with token types. It also
provides a list of extensible structured tokens, with map names and DDL definitions of
each.
Buffer Declarations The DNS subsystem provides the following buffer declarations for SPI message
buffers.
ZDNS-DDL-MSG-BUFFER
is a message buffer whose size is that recommended for command messages and
for responses in which each reply message contains a single response record. It
has the following structure:
def ZDNS-DDL-MSG-BUFFER.
02 Z-MSGCODE type ZSPI-DDL-INT.
02 Z-BUFLEN type ZSPI-DDL-UINT.
02 Z-OCCURS type ZSPI-DDL-UINT.
02 Z-FILLER type ZSPI-DDL-BYTE
occurs 0 to 4190 times
depending on Z-OCCURS.
