| <p> |
| A pointer to the data pattern of size <code class="varname">pattern_size</code> |
| in bytes. <code class="varname">pattern</code> will be used to fill a region |
| in <code class="varname">buffer</code> starting at <code class="varname">offset</code> |
| and is <code class="varname">size</code> bytes in size. The data pattern |
| must be a scalar or vector integer or floating-point data type. For |
| example, if <code class="varname">buffer</code> is to be filled with a pattern of |
| <span class="type">float4</span> values, then <code class="varname">pattern</code> will be a pointer |
| to a <span class="type">cl_float4</span> value and <code class="varname">pattern_size</code> |
| will be <code class="code">sizeof(cl_float4)</code>. The maximum value of |
| <code class="varname">pattern_size</code> is the size of the largest integer |
| or floating-point vector data type supported by the OpenCL device. |

| pointed to by <code class="varname">event_wait_list</code> must be valid |
| and <code class="varname">num_events_in_wait_list</code> must be greater |

| act as synchronization points. The context associated with events in |
| <code class="varname">event_wait_list</code> and <code class="varname">command_queue</code> must |
