The OpenCL extension <code class="function">cl_khr_byte_addressable_store</code> removes certain restrictions on built-in types <span class="type">char</span>, <span class="type">uchar</span>, <span class="type">char2</span>, <span class="type">uchar2</span>, <span class="type">short</span>,
and <span class="type">half</span>. An application that wants to be able to write to elements of a pointer (or struct) that
are of type <span class="type">char</span>, <span class="type">uchar</span>, <span class="type">char2</span>, <span class="type">uchar2</span>, <span class="type">short</span>, <span class="type">ushort</span>, and <span class="type">half</span> will need to include
the <code class="function">#pragma OPENCL EXTENSION cl_khr_byte_addressable_store : enable</code> directive before any code that performs writes that may not be supported.
