NAME
clusternode_avail - determines if node is up
SYNOPSIS
#include <sys/cluster.h>
int clusternode_avail(clusternode_t nodenum);
cc [flag ...] file -lcluster [library ...]
DESCRIPTION
clusternode_avail() determines if the node specified by nodenum
is up and returns an appropriate value to the caller to indicate that.
This determination is made based on the node state CLUSTERNODE_UP.
For details about node states, see
cluster(8ssi).
The details of the argument to clusternode_avail are:
- nodenum
-
The number of the node for which information is returned. Values must be
between 1 and the maximum number of nodes allowed by the cluster
configuration. This number is the value returned by cluster_maxnodes().
RETURN VALUE
clusternode_avail() returns a value of 1 if the node is in
CLUSTERNODE_UP state.
A value of 0 is returned by clusternode_avail() if the node
is not in CLUSTERNODE_UP state.
If nodenum is invalid, or, if clusternode_avail() encounters
an error, while processing the request it returns -1 and sets
errno to indicate the cause of the error.
