.SH "NAME"
wait_group_events \- Wait for events that identify the async_work_group_copy operations to complete\&.
.SH ""
.HP \w'void\ wait_group_events('u
.BI "void wait_group_events(int\ " "num_events" ", event_t\ *" "event_list" ");"
.SH "DESCRIPTION"
.PP
Wait for events that identify the
\fBasync_work_group_copy\fR(3clc)
operations to complete\&. The event objects specified in
\fIevent_list\fR
will be released after the wait is performed\&.
.PP
This function must be encountered by all work\-items in a work\-group executing the kernel with the same
\fInum_events\fR
and event objects specified in
\fIevent_list\fR; otherwise the results are undefined\&.
.SH "NOTES"
.PP
The kernel must wait for the completion of all async copies using the
\fBwait_group_events\fR
built\-in function before exiting; otherwise the behavior is undefined\&.
