Provided by: libvotequorum-dev_3.1.6-1ubuntu1_amd64 bug

NAME
       votequorum_qdevice_master_wins - Sets or clears quorum device master_wins flag


SYNOPSIS
       #include <corosync/votequorum.h>

       int votequorum_qdevice_master_wins(votequorum_handle_t handle const char name, unsigned int allow);


DESCRIPTION
       The  votequorum_qdevice_master_wins  informs  votequorum  whether or not the currently registered qdevice
       subsystem supports 'master_wins' mode (default 0).  This mode allows the qdevice to effectively take over
       the  quorum  calculations  of  votequorum.  Any node with an active qdevice that also has master_wins set
       becomes quorate regardless of the node votes of the cluster. It is  left  up  to  the  qdevice  subsystem
       itself  (not  part  of  votequorum)  to  communicate across the nodes or otherwise provide some system of
       deciding which nodes will be part of the quorate cluster, if any. eg They may be the set  of  nodes  that
       has access to a quorum disk.
       name  The  name of the currently registered quorum device on this node. This must match the existing name
       known to votequorum.
       allow 0 (the default) means that master_wins is not active on this node.  1  means  that  master_wins  is
       active on this node.

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