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.
