Required Object States for Continuation
End of Continuation
The Pathway subsystem management programming interface is designed to return a
context token during continuation whenever there is a response in the response buffer.
As a result, the Pathway subsystem always returns an empty response for the last
record of a continuation. The value ZPWY-ERR-PM-NODATA denotes an empty
response buffer, as well as the end of the response continuation dialog.
You must code your management application to expect and interpret
ZPWY-ERR-PM-NODATA during response continuation; this token is the final
indication of the end of continuation.
Values for Specifying Continuation
These tokens represent the predefined values assigned to TS/MP object name fields in
object-selector tokens:
These values have the same meaning as the asterisk (*) used in the PATHCOM
commands. For example, to implement the PATHCOM INFO SERVER * command,
you use the predefined value ZPWY-VAL-ALLSC in the object-selector token
ZPWY-DDL-SEL-SC.
Required Object States for Continuation
For each type of command, continuation only acts on objects in a specific state. If an
object is not in the required state, responses might not be returned for all objects or
subobjects requested. Table 3-3 indicates the required state for each Pathway
subsystem command that supports continuation and each object type applicable to that
command.
