ZSPI Data Definitions

Subsystem Numbers

The SPI definitions include a subsystem number for every NonStop Kernel subsystem

that has a programmatic command interface based on SPI, reports events through

EMS, or defines error information in SPI error lists. Your program should use the

symbolic names for these subsystem numbers. The names are all of the form ZSPI-

SSN-

subsys, where subsys is the appropriate four-character subsystem

abbreviation. See Appendix D, NonStop Kernel Subsystem Numbers and

Abbreviations.

Miscellaneous Values

The SPI standard definition files include these standard value names for tokens and

SPI procedure-call parameters. Use these names in your programs whenever

appropriate.

ZSPI-VAL-ALLOW-SEGMENTS

A requester assigns this value to ZSPI-TKN-ALLOW and includes that token in a

command message to ask a server for a segmented response.

ZSPI-VAL-CMDHDR

ZSPI-VAL-CMDHDR is the value of the header-type field of the SPI message header

for a command or response. Use this value for the SSINIT parameter

header-type

when initializing a command or response buffer.

ZSPI-VAL-EVTHDR

ZSPI-VAL-EVTHDR is the value of the header-type field of the SPI message header

for an event message.

ZSPI-VAL-FALSE

ZSPI-VAL-FALSE is the Boolean value FALSE, represented internally by the integer 0.

This named value is not supported by COBOL. To interpret Boolean values in COBOL,

see Section 7, SPI Programming in COBOL

constant ZSPI-VAL-ALLOW-SEGMENTS value is -1.

constant ZSPI-VAL-CMDHDR value is 0.

constant ZSPI-VAL-EVTHDR value is 1.

constant ZSPI-VAL-FALSE value is 0.
