NAME¶
votequorum_dispatch - Dispatches callbacks from the votequorum service
SYNOPSIS¶
#include <corosync/votequorum.h>
int votequorum_dispatch(votequorum_handle_t handle,
votequorum_dispatch_t *dispatch_types);
DESCRIPTION¶
The
votequorum_dispatch function is used to dispatch configuration
changes.
Each application may have several connections to the votequorum API. Each
application uses the
handle argument to uniquely identify the
connection.
The
dispatch_types argument is used to identify the type of dispatch to
execute. The possible types are defined by the structure:
typedef enum {
CS_DISPATCH_ONE,
CS_DISPATCH_ALL,
CS_DISPATCH_BLOCKING
} votequorum_dispatch_t;
The dispatch values have the following meanings:
- CS_DISPATCH_ONE
- Dispatch at least one callback, blocking until the callback
is dispatched.
- CS_DISPATCH_ALL
- Dispatch all waiting callbacks without blocking to wait for
any callbacks.
- CS_DISPATCH_BLOCKING
- Dispatch all callbacks blocking indefinitely. This is used
in a threaded program where a thread is created, and then
votequorum_dispatch() is called immediately from the created thread to
execute callbacks.
RETURN VALUE¶
This call returns the CS_OK value if successful, otherwise an error is returned.
ERRORS¶
The errors are undocumented.
