NAME

6       votequorum_dispatch - Dispatches callbacks from the votequorum service
7

SYNOPSIS

9       #include <corosync/votequorum.h>
10
11       int votequorum_dispatch(votequorum_handle_t handle, cs_dispatch_flags_t
12       *dispatch_types);
13

DESCRIPTION

15       The votequorum_dispatch function  is  used  to  dispatch  configuration
16       changes.
17
18       Each  application  may  have several connections to the votequorum API.
19       Each application uses the handle argument to uniquely identify the con‐
20       nection.
21
22       The dispatch_types argument is used to identify the type of dispatch to
23       execute.  The possible types are defined by the structure:
24
25       typedef enum {
26               CS_DISPATCH_ONE = 1,
27               CS_DISPATCH_ALL = 2,
28               CS_DISPATCH_BLOCKING = 3,
29               CS_DISPATCH_ONE_NONBLOCKING = 4
30       } cs_dispatch_flags_t;
31
32       The dispatch values have the following meanings:
33
34       CS_DISPATCH_ONE
35              Dispatch at least one callback, blocking until the  callback  is
36              dispatched.
37
38       CS_DISPATCH_ALL
39              Dispatch  all waiting callbacks without blocking to wait for any
40              callbacks.
41
42       CS_DISPATCH_BLOCKING
43              Dispatch all callbacks blocking indefinitely.  This is used in a
44              threaded program where a thread is created, and then quorum_dis‐
45              patch() is called immediately from the created thread to execute
46              callbacks.
47
48       CS_DISPATCH_ONE_NONBLOCKING
49              Dispatch  at most one callback. If there is no pending callback,
50              CS_ERR_TRY_AGAIN is returned.
51
52

RETURN VALUE

54       This call returns the CS_OK value if successful, otherwise an error  is
55       returned.
56

59
60       CS_ERR_INVALID_PARAM Invalid argument

64       CS_ERR_LIBRARY The connection failed
65
66       CS_ERR_INTERRUPT System call interrupted by a signal
