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 quorum 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.
