| <h4><a id="id-1.6.8"></a>Accessing mapped regions of a memory object</h4> |
| <p> |
| This section describes the behavior of OpenCL commands that access |
| mapped regions of a memory object. |
| </p> |
| <p> |
| The contents of the region of a memory object and associated memory objects |
| (sub-buffer objects or 1D image buffer objects that overlap this region) mapped |
| for writing (i.e. <code class="constant">CL_MAP_WRITE</code> or |
| <code class="constant">CL_MAP_WRITE_INVALIDATE_REGION</code> is set in <code class="varname">map_flags</code> |
| argument to <a class="citerefentry" href="clEnqueueMapBuffer.html"><span class="citerefentry"><span class="refentrytitle">clEnqueueMapBuffer</span></span></a> |
| or <a class="citerefentry" href="clEnqueueMapImage.html"><span class="citerefentry"><span class="refentrytitle">clEnqueueMapImage</span></span></a>) are |
| considered to be undefined until this region is unmapped. |
| </p> |
| <p> |
| Multiple commands in command-queues can map a region or overlapping regions of a memory |
| object and associated memory objects (sub-buffer objects or 1D image buffer objects that |
| overlap this region) for reading |
| (i.e. <code class="varname">map_flags</code> = <code class="constant">CL_MAP_READ</code>). |
| The contents of the regions of a memory object mapped for reading can also be read by kernels |
| and other OpenCL commands (such as |
| <a class="citerefentry" href="clEnqueueCopyBuffer.html"><span class="citerefentry"><span class="refentrytitle">clEnqueueCopyBuffer</span></span></a>) |
| executing on a device(s). |
| </p> |
| <p> |
| Mapping (and unmapping) overlapped regions in a memory object and/or associated memory |
| objects (sub-buffer objects or 1D image buffer objects that overlap this region) for writing |
| is an error and will result in <code class="constant">CL_INVALID_OPERATION</code> error returned by |
| <a class="citerefentry" href="clEnqueueMapBuffer.html"><span class="citerefentry"><span class="refentrytitle">clEnqueueMapBuffer</span></span></a> |
| or <a class="citerefentry" href="clEnqueueMapImage.html"><span class="citerefentry"><span class="refentrytitle">clEnqueueMapImage</span></span></a>. |
| </p> |
| <p> |
| If a memory object is currently mapped for writing, the application must ensure that the memory |
| object is unmapped before any enqueued kernels or commands that read from or write to this |
| memory object or any of its associated memory objects (sub-buffer or 1D image buffer objects) |
| or its parent object (if the memory object is a sub-buffer or 1D image buffer object) begin |
| execution; otherwise the behavior is undefined. |

| object (if the memory object is a sub-buffer or 1D image buffer object) begin execution; |
| otherwise the behavior is undefined. |
| </p> |
| <p> |
| A memory object is considered as mapped if there are one or more active mappings for the |
| memory object irrespective of whether the mapped regions span the entire memory object. |
| </p> |
| <p> |
| Accessing the contents of the memory region referred to by the mapped pointer that has |
| been unmapped is undefined. |
