Handle
A handle into the cfg library. returned from initialize and needed for all other calls
LinkStatus
Status of a link inside NodeStatus struct
NodeStatus
Structure returned from node_status_get, shows all the details of a node that is known to corosync, including all configured links

Enums§

NodeStatusVersion
Version of the NodeStatus structure returned from node_status_get
ShutdownFlags

local_get
Get the local NodeId
node_status_get

reply_to_shutdown
Reply to a shutdown request with Yes or No ShutdownReply
