11 int votequorum_getinfo(votequorum_handle_t *handle, unsigned int
12 nodeid, struct votequorum_info *info);
13
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

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

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