clEnqueueMarkerWithWaitList - Enqueues a marker command which waits for either a list of events to complete, or all previously enqueued commands to complete.
cl_int clEnqueueMarkerWithWaitList(cl_command_queue command_queue, cl_uint num_events_in_wait_list, const cl_event *event_wait_list, cl_event *event);
If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns.
If event_wait_list is NULL, then this particular command waits until all previous enqueued commands to command_queue have completed.
Enqueues a marker command which waits for either a list of events to complete, or if the list is empty it waits for all commands previously enqueued in command_queue to complete before it completes. This command returns an event which can be waited on, i.e. this event can be waited on to insure that all events either in the event_wait_list or all previously enqueued commands, queued before this command to command_queue, have completed.
Returns CL_SUCCESS if the function executed successfully, or one of the errors below:
