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

NAME

       votequorum_qdevice_register - Registers a new quorum device

SYNOPSIS

       #include <corosync/votequorum.h>

       int votequorum_qdevice_register(votequorum_handle_t handle, const char * name);

DESCRIPTION

       The  votequorum_qdevice_register  is  used  to  register a new quorum device. A quorum device is an external way of adding votes to a small
       cluster. The quorum device is, in effect, a pseudo node in the cluster that provide votes based on some external device, usually  a  shared
       disk partition or perhaps a network router.
       This  call creates the device but does not mark it active.  votequorum_qdevice_poll must be called for the votes to be included in the quo-
       rum calculation.
       name is string containing an informative name for the quorum device. It is simply stored by votequorum and used in the display of corosync-
       quorumtool, it can be a maximum of 254 characters.
       The  number  of votes contributed by the quorum device is already known to votequorum, it is set in cmap quorum.device.votes and not by the
       device.
       Note that it is the responsibility of the quorum device subsystem (not provided as part of votequorum) to keep all nodes  informed  of  the
       quorum device status.

RETURN VALUE

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