| <a class="citerefentry" href="async_work_group_copy.html"><span class="citerefentry"><span class="refentrytitle">async_work_group_copy</span></span></a> |
| operations to complete. The event objects specified in <code class="varname">event_list</code> |

| This function must be encountered by all work-items in a work-group executing the |
| kernel with the same <code class="varname">num_events</code> and event objects specified in |
| <code class="varname">event_list</code>; otherwise the results are undefined. |
| This rule applies to ND-ranges implemented with uniform |
| and non-uniform work-groups. |

| <h2>Notes</h2> |
| <p> |
| The kernel must wait for the completion of all async copies using the |
| <code class="function">wait_group_events</code> built-in function before exiting; otherwise the |
| behavior is undefined. |
