NAME
evs_dispatch - Dispatches callbacks from the EVS service
SYNOPSIS
#include <openais/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.
