SYNOPSIS

#include <corosync/votequorum.h>

int votequorum_getinfo(votequorum_handle_t *handle, unsigned int nodeid, struct votequorum_info *info);

DESCRIPTION

The votequorum_getinfo function is used to get information about the voting system and its nodes.

The nodeid argument indicates which node information should be stored in the votequorum_info structure.

The votequorum_info structure is defined as follows:

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]; };

The node_state is defined as:

#define VOTEQUORUM_NODESTATE_MEMBER 1 #define VOTEQUORUM_NODESTATE_DEAD 2 #define VOTEQUORUM_NODESTATE_LEAVING 3

The flags are defined as:

#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

The members starting node_ hold information specific to the requested nodeid, the other are general to the voting system.

RETURN VALUE

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