NAME

evs_dispatch - Dispatches callbacks from the EVS service  

SYNOPSIS

#include <corosync/evs.h>

int evs_dispatch(evs_handle_t handle, evs_dispatch_t *dispatch_types);  

DESCRIPTION

The evs_dispatch function is used to dispatch configuration changes or messages from the extended virtual synchrony API.

Each application may have several connections to the EVS 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 {
        EVS_DISPATCH_ONE,
        EVS_DISPATCH_ALL,
        EVS_DISPATCH_BLOCKING
} evs_dispatch_t;

The dispatch values have the following meanings:

EVS_DISPATCH_ONE
Dispatch atleast one callback, blocking until the callback is dispatched.
EVS_DISPATCH_ALL
Dispatch all waiting callbacks without blocking to wait for any callbacks.
EVS_DISPATCH_BLOCKING
Dispatch all callbacks blocking indefinately. This is used in a threaded program where a thread is created, and then evs_dispatch() is called immediately from the created thread to execute callbacks.

 

RETURN VALUE

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

 

ERRORS

The errors are undocumented.
