Wait on a specified asynchronous event.
MCO_RET mco_async_event_wait( /*IN*/ mco_db_h db, /*IN*/ in event_id);
| db | The database handle that was established by mco_db_connect() |
|
event_id |
The identifier assigned to the event in the generated interface header file |
This function blocks the thread until the event referenced by
event_idoccurs or the application explicitly releases the event handler.
| MCO_S_OK | The event occurred |
| MCO_E_INVALID_HANDLE | The database handle is invalid |
| MCO_S_EVENT_RELEASED | The event was released by the application |

mco_db_h db = descriptor->db_connection;
while ( MCO_S_OK == mco_async_event_wait(db, MCO_EVENT_newEvent) )

count++;
}
printf("\tExiting NewEventHandler. Number of calls : %d\n", count);
