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.
