If the `event_wait_list` and the `event` arguments are not NULL, the `event` argument should not refer to an element of the `event_wait_list` array.


[[example]]
== Example

As example of how to specify the size of a kernel, suppose a 1D kernel should be enqueued with

[source,c]
----
global_work_offset[0] = 2;
global_work_size[0] = 4;
local_work_size[0] = 2;
----

This will create 4 work-items with the following IDs:

[cols="1a,1a,1a", options="header"]
|===

||Global ID|Local ID
|work-item 1|2|0
|work-item 2|3|1
|work-item 3|4|0
|work-item 4|5|1
