       int votequorum_setexpected(votequorum_handle_t handle, int expected_votes);

DESCRIPTION

       The  votequorum_setexpected  function  is  used to change the expected votes in the cluster. Expected votes is used to calculate quorum and
       should normally be the total number of votes that will exist when all the expected nodes are joined. Quorum will usually be  half  of  this
       (rounded up).   It is not possible to set expected votes up so that it makes the cluster inquorate using this command.

RETURN VALUE

       This call returns the CS_OK value if successful, otherwise an error is returned.

ERRORS

       CS_ERR_TRY_AGAIN Resource temporarily unavailable

       CS_ERR_INVALID_PARAM Invalid argument

       CS_ERR_ACCESS Permission denied

       CS_ERR_INTERRUPT System call inturrupted by a signal

       CS_ERR_NOT_SUPPORTED The requested protocol/functuality not supported

       CS_ERR_MESSAGE_ERROR Incorrect auth message received

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

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

RETURN VALUE

       This call returns the CS_OK value if successful, otherwise an error is returned.
