current position
current position. The location in the SPI buffer of the token whose token code, token
value, or attribute has just been retrieved. Scans for the next token code (with the
operations ZSPI-TKN-NEXTCODE and ZSPI-TKN-NEXTTOKEN) begin at the current
position but always return a token code beyond the current position. See also next
position and initial position.
current token. The token in the current position. See current position.
data communications standard definitions. The set of declarations provided by HP for
use in all management applications that manage, or retrieve event messages from,
data communications subsystems for NonStop servers. Names of data
communications standard definitions start with either ZCOM or ZCMK. See also
definition, definition files, SPI standard definitions, and EMS standard definitions.
data list. A grouping of tokens used to separate response records within an SPI message
for a response or to enclose a single response record if the program so requests. A
data list consists of a list token that denotes a data list (different from the token that
starts an error list or a generic list), followed by a response record and an end-list
token. See response record.
data-portion token. A token within the body of an SPI message, as opposed to within the
header. Data-portion tokens are placed in the buffer using SSPUT or SSPUTTKN.
Some data-portion tokens can occur multiple times in the buffer, and most can be
enclosed in lists. Programs can set the current position to these tokens and can
retrieve their values using the NEXTCODE and NEXTTOKEN operations. See also
header token.
Define Process library. A set of TACL routines that allow the user to run background
server processes—that is, server processes that continue running until they are
explicitly stopped—so that management applications can send commands to a number
of subsystems without the overhead of creating a new server process for each
command. The library includes routines to define run parameters for a background
process, to start and stop the process, to manage its input and output, and to clear the
input queue or the output queue for the process.
definition. One of the declarations provided by HP for use in applications that call the SPI
procedures. These definitions are provided in definition files.
definition files. A set of files containing declarations for use in applications that call the SPI
procedures. SPI has a standard definition file for DDL and one for each of the
programming languages supporting SPI. The latter files are derived from the DDL
definition file. Likewise, each subsystem that has a token-oriented programmatic
interface has one definition file for DDL and one for each programming language.
Some subsystems—for instance, data communications subsystems—have additional,
shared definition files. See also data communications standard definitions, SPI
standard definitions, EMS standard definitions, and subsystem definitions.
