NAME

       quorum_overview - Quorum Library Overview

OVERVIEW

       The  quorum library is delivered with the corosync project. It is the external interface to the quorum service. This service is loaded into
       all nodes in a corosync cluster and track the quorum status of a node. In order for quorum service to be useful, a quorum provider must	be
       configured.

       The library provides a mechanism to:

       * Query the quorum status

       * Receive notifications of quorum state changes

BUGS

       No known bugs at the time of writing. The authors are from outerspace. Deal with it.

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

NAME

       quorum_fd_get - Dispatches callbacks from the quorum service

SYNOPSIS

       #include <corosync/quorum.h>

       int quorum_fd_get(quorum_handle_t handle, int *fd);

DESCRIPTION

       The quorum_fd_get function is used to retrieve the file descriptor that may be used with the poll system call to determine when quorum_dis-
       patch(3) won't block.  The handle argument may not be used directly with poll because it is not the file descriptor, but instead an  inter-
       nal identifier used by the quorum library.

RETURN VALUE

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

ERRORS

       CS_ERR_TRY_AGAIN Resource temporarily unavailable

       CS_ERR_INVALID_PARAM Invalid argument

       CS_ERR_ACCESS Permission denied

       CS_ERR_LIBRARY The connection failed

       CS_ERR_INTERRUPT System call inturrupted by a signal

       CS_ERR_NOT_SUPPORTED The requested protocol/functuality not supported

       CS_ERR_MESSAGE_ERROR Incorrect auth message received

       CS_ERR_NO_MEMORY Not enough memory to completed the requested task
