SYNOPSIS

9       #include <corosync/votequorum.h>
10
11       int   votequorum_getinfo(votequorum_handle_t   *handle,   unsigned  int
12       nodeid, struct votequorum_info *info);

DESCRIPTION

15       The votequorum_getinfo function is used to get  information  about  the
16       voting system and its nodes.
17
18       The  nodeid  argument indicates which node information should be stored
19       in the votequorum_info structure.
20
21       The votequorum_info structure is defined as follows:
22
23
24       struct votequorum_info {
25               unsigned int node_id;
26               unsigned int node_state;
27               unsigned int node_votes;
28               unsigned int node_expected_votes;
29               unsigned int highest_expected;
30               unsigned int total_votes;
31               unsigned int quorum;
32               unsigned int flags;
33               unsigned int qdevice_votes;
34               char qdevice_name[VOTEQUORUM_QDEVICE_MAX_NAME_LEN];
35       };
36
37       The node_state is defined as:
38
39       #define VOTEQUORUM_NODESTATE_MEMBER     1
40       #define VOTEQUORUM_NODESTATE_DEAD       2
41       #define VOTEQUORUM_NODESTATE_LEAVING    3
42
43       The flags are defined as:
44
45       #define VOTEQUORUM_INFO_TWONODE                 1
46       #define VOTEQUORUM_INFO_QUORATE                 2
47       #define VOTEQUORUM_INFO_WAIT_FOR_ALL            4
48       #define VOTEQUORUM_INFO_LAST_MAN_STANDING       8
49       #define VOTEQUORUM_INFO_AUTO_TIE_BREAKER       16
50       #define VOTEQUORUM_INFO_ALLOW_DOWNSCALE        32
51       #define VOTEQUORUM_INFO_QDEVICE_REGISTERED     64
52       #define VOTEQUORUM_INFO_QDEVICE_ALIVE         128
53       #define VOTEQUORUM_INFO_QDEVICE_CAST_VOTE     256
54       #define VOTEQUORUM_INFO_QDEVICE_MASTER_WINS   512
55
56
57       The members starting node_ hold information specific to  the  requested
58       nodeid, the other are general to the voting system.
