HP-UX SNAplus2 R7 NOF Programmer's Guide

NOF API Verbs
QUERY_NN_TOPOLOGY_STATS
The list_options parameter was set to AP_LIST_INCLUSIVE to list all entries starting from the
supplied name, but the node_name parameter was not valid.
AP_INVALID_LIST_OPTION
The list_options parameter was not set to a valid value.
Appendix B, Common Return Codes lists further secondary return codes associated with
AP_PARAMETER_CHECK
,
which are common to all NOF verbs.
3.141.5 Returned Parameters: Function Not Supported
If the verb does not execute successfully because the local node is not a network node, SNAplus2 returns the
following parameters:
primary_rc
AP_FUNCTION_NOT_SUPPORTED
The local node is not a network node. This verb can be used only at a network node.
3.141.6 Returned Parameters: Other Conditions
Appendix B, Common Return Codes lists further combinations of primary and secondary return codes that are
common to all NOF verbs.
3.142 QUERY_NN_TOPOLOGY_STATS
QUERY_NN_TOPOLOGY_STATS returns statistical information about the topology database. It can be used only
if the SNAplus2 node is a network node, and is not valid if it is an end node.
This verb must be issued to a running node.
