NAME

cpg_dispatch - Dispatches callbacks from the CPG service  

SYNOPSIS

#include <corosync/cpg.h>

int cpg_dispatch(cpg_handle_t handle, cpg_dispatch_t *dispatch_types);  

DESCRIPTION

The cpg_dispatch function is used to dispatch configuration changes or messages from the closed process groups API.

Each application may have several connections to the CPG 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 {
        CPG_DISPATCH_ONE,
        CPG_DISPATCH_ALL,
        CPG_DISPATCH_BLOCKING
} cpg_dispatch_t;

The dispatch values have the following meanings:

CPG_DISPATCH_ONE
Dispatch atleast one callback, blocking until the callback is dispatched.
CPG_DISPATCH_ALL
Dispatch all waiting callbacks without blocking to wait for any callbacks.
CPG_DISPATCH_BLOCKING
Dispatch all callbacks, blocking indefinitely. This is used in a threaded program where a thread is created, and then cpg_dispatch() is called immediately from the created thread to execute callbacks.

 

RETURN VALUE

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

 

ERRORS

The errors are undocumented.
