quorum_trackstart - Enable callbacks notification.
#include <corosync/quorum.h> int quorum_trackstart(quorum_handle_t *handle, unsigned int flags);
The quorum_trackstart function is used to enable callbacks notification from the quorum API. Every time the voting configuration changes (eg a node joins or leave the cluster) or the quorum status change, the notification is queued. The notification is dispatched via quorum_dispatch() function that will execute the callback. 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
This call returns the CS_OK value if successful, otherwise an error is returned.
