To wait for events to complete, call the function
cl_int clWaitForEvents( cl_uint num_events, const cl_event* event_list);
num_events is the number of events in event_list.
event_list is a pointer to a list of event object handles.
This function waits on the host thread for commands identified by event
objects in event_list to complete.
A command is considered complete if its execution status is
CL_COMPLETE or a
The events specified in event_list act as synchronization points.
CL_SUCCESS if the execution status of all events
in event_list is
Otherwise, it returns one of the following errors:
CL_INVALID_VALUEif num_events is zero or event_list is
CL_INVALID_CONTEXTif events specified in event_list do not belong to the same context.
CL_INVALID_EVENTif event objects specified in event_list are not valid event objects.
CL_EXEC_STATUS_ERROR_FOR_EVENTS_IN_WAIT_LISTif the execution status of any of the events in event_list is a negative integer value. This error code is missing before version 1.1.
CL_OUT_OF_RESOURCESif there is a failure to allocate resources required by the OpenCL implementation on the device.
CL_OUT_OF_HOST_MEMORYif there is a failure to allocate resources required by the OpenCL implementation on the host.
