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 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
