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. SEE ALSO

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

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 SEE ALSO
