NAME

clusternode_info - returns detailed information about a node

SYNOPSIS

#include <sys/cluster.h>

int clusternode_info(clusternode_t nodenum,
                     int sizeof(clusternode_info_t),
                     clusternode_info_t *nodeinfo);

cc [flag ...] file -lcluster [library ...]

DESCRIPTION

Returns cluster node status information into nodeinfo for the node specfied by nodenum.

For details about node status information, see the cluster(8ssi) manual page.

PARAMETERS

nodenum: The number of the cluster node for which information is returned. Values must be between 1 and the value returned by cluster_maxnodes(3ssi).
nodeinfo: A pointer to a structure of type clusternode_info_t that contains state, transition, and other information for the node specified.

RETURN VALUE

Upon successful execution, clusternode_info returns 0, otherwise it returns -1 and sets errno to indicate the cause of the error.

ERRORS

If the call to clusternode_info fails, errno is set to the following value to indicate the cause of the error:

EINVAL: The specified nodenum was not a valid cluster node or the nodeinfo pointer was invalid.
