ZCOM Tables and Data Structures

Node Entries Table

FLAGS - Node status and internal flags

This bit-field structure contains bits to maintain state and other internal information about this node. The contents of this field are as follows:

	FLAGS.event -	Set to 1 if there is at least one application that wants to be
		notified of a status change for the node.
	FLAGS.valid -	Set to 1 if this node entry in the table is valid; that is,
		currently defined and in use.
	FLAGS.status -	Set to 1 if this node is currently UP. The status bit indicates
		whether a remote node is usable. If this bit is not set, the
		LDM will reject all requests to that node with a
		ZENDOWN (-61) error. For a local node, the status bit
		indicates that the ZNODE daemon is running properly.
	FLAGS.local -	Set to 1 if this node entry in the table represents the local
		node.
	STATS - Statistics for this node
	This field is a data structure that contains some statistics on the data
	traffic for this node. The layout of this structure is shown in Table 3-5.
Table 3-5	STATS Data Structure
Field Name	Field Description		Field Type	Size
				(Bytes)
icount	Number of incoming messages		uns.int	4
ibytes	Number of incoming bytes		uns.int	4
ocount	Number of outgoing messages		uns.int	4
obytes	Number of outgoing bytes		uns.int	4

NDSHZRVRS - Pointer to a list of receivers for node status events.

This field contains a pointer to a linked list of applications to be notified whenever this node changes state. Whenever this node changes state from up-to-down or down-to-up, a node status system event message will be sent to each program in this linked list. That is, those applications that have issued a zevent_rcvr() call to receive node status events. This field will be set to zero if there are no applications to be notified.
