VOTEQUORUM_QDEVICE_UPDATE(3)			    Corosync Cluster Engine Programmer's Manual 		      VOTEQUORUM_QDEVICE_UPDATE(3)

NAME

       votequorum_qdevice_update - Updates quorum device name

SYNOPSIS

       #include <corosync/votequorum.h>

       int votequorum_qdevice_update(votequorum_handle_t handleconst char oldname, const char newname);

DESCRIPTION

       The  votequorum_qdevice_update  is used to change the name of the quorum device to corosync. The name of q quorum device is purely informa-
       tional and has no significance to votequorum itself, but it's useful for the name (displayed by corosync-quorumtool) to reflect the  actual
       device contributing votes to quorum to avoid user confusion.

NAME

       votequorum_trackstart - Enable callbacks notification.

SYNOPSIS

       #include <corosync/votequorum.h>

       int votequorum_trackstart(votequorum_handle_t *handle, uint64_t context, unsigned int flags);

DESCRIPTION

       The votequorum_trackstart function is used to enable callbacks notification from the votequorum API.

       Every  time  the  voting  configuraton  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 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
