NAME¶

confdb_dispatch - Dispatches callbacks from the CONFDB service

SYNOPSIS¶

#include <corosync/confdb.h>

int confdb_dispatch(confdb_handle_t handle, confdb_dispatch_t *dispatch_types);

DESCRIPTION¶

The confdb_dispatch function is used to dispatch configuration changes.

Each application may have several connections to the CONFDB 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 {


        CONFDB_DISPATCH_ONE,


        CONFDB_DISPATCH_ALL,


        CONFDB_DISPATCH_BLOCKING
} confdb_dispatch_t;

The dispatch values have the following meanings:

CONFDB_DISPATCH_ONE

Dispatch at least one callback, blocking until the callback is dispatched.

CONFDB_DISPATCH_ALL

Dispatch all waiting callbacks without blocking to wait for any callbacks.

CONFDB_DISPATCH_BLOCKING

Dispatch all callbacks blocking indefinitely. This is used in a threaded program where a thread is created, and then confdb_dispatch() is called immediately from the created thread to execute callbacks.

RETURN VALUE¶

This call returns the CONFDB_OK value if successful, otherwise an error is returned.

ERRORS¶

The errors are undocumented.
