.TH VOTEQUORUM_GETINFO 3 @BUILDDATE@ "corosync Man Page" "Corosync Cluster Engine Programmer's Manual"
.SH NAME
votequorum_getinfo \- Get information about the VoteQuorum service
.SH SYNOPSIS
.B #include <corosync/votequorum.h>
.sp
.BI "int votequorum_getinfo(votequorum_handle_t *" handle ", unsigned int " nodeid ", struct votequorum_info *" info ");"
.SH DESCRIPTION
The
.B votequorum_getinfo
function is used to get information about the voting system and its nodes.
The
.I nodeid
argument indicates which node information should be stored in the votequorum_info structure.
The votequorum_info structure is defined as follows:
.nf
struct votequorum_info {
unsigned int node_id;
unsigned int node_state;
unsigned int node_votes;
unsigned int node_expected_votes;
unsigned int highest_expected;
unsigned int total_votes;
unsigned int quorum;
unsigned int flags;
unsigned int qdevice_votes;
char qdevice_name[VOTEQUORUM_QDEVICE_MAX_NAME_LEN];
};
.fi
The node_state is defined as:
.nf
#define VOTEQUORUM_NODESTATE_MEMBER 1
#define VOTEQUORUM_NODESTATE_DEAD 2
#define VOTEQUORUM_NODESTATE_LEAVING 3
.fi
The flags are defined as:
.nf
#define VOTEQUORUM_INFO_TWONODE 1
#define VOTEQUORUM_INFO_QUORATE 2
#define VOTEQUORUM_INFO_WAIT_FOR_ALL 4
#define VOTEQUORUM_INFO_LAST_MAN_STANDING 8
#define VOTEQUORUM_INFO_AUTO_TIE_BREAKER 16
#define VOTEQUORUM_INFO_ALLOW_DOWNSCALE 32
#define VOTEQUORUM_INFO_QDEVICE_REGISTERED 64
#define VOTEQUORUM_INFO_QDEVICE_ALIVE 128
#define VOTEQUORUM_INFO_QDEVICE_CAST_VOTE 256
#define VOTEQUORUM_INFO_QDEVICE_MASTER_WINS 512
.fi
.PP
The members starting node_ hold information specific to the requested nodeid, the other are
general to the voting system.
.SH RETURN VALUE
This call returns the CS_OK value if successful, otherwise a generic error is returned.
