wait_group_events

Wait for events that identify the async_work_group_copy operations to complete.

void wait_group_events ( int num_events,
  event_t *event_list)

Description

Wait for events that identify the async_work_group_copy operations to complete. The event objects specified in event_list will be released after the wait is performed.

This function must be encountered by all work-items in a work-group executing the kernel with the same num_events and event objects specified in event_list; otherwise the results are undefined.

Notes

The kernel must wait for the completion of all async copies using the wait_group_events built-in function before exiting; otherwise the behavior is undefined.
