votequorum_trackstart - Enable callbacks notification.
#include <corosync/votequorum.h> int votequorum_trackstart(votequorum_handle_t *handle, uint64_t context, unsigned int flags);
The votequorum_trackstart function is used to enable callbacks notification from the votequorum API. Every time the voting configuration changes (eg a node joins or leave the cluster) or the quorum status change or the expected votes changes, the notification is queued. The notification is dispatched via votequorum_dispatch() function that will execute the callback. The context option allows one to set a tracking context. The flags argument is defined by one or more of the following values and values can be bitwise-or'd #define CS_TRACK_CURRENT 0x01 #define CS_TRACK_CHANGES 0x02 #define CS_TRACK_CHANGES_ONLY 0x04
