<p><code>CL_&#8203;KERNEL_&#8203;ARG_&#8203;TYPE_&#8203;CONST</code> is returned for
<code>CL_&#8203;KERNEL_&#8203;ARG_&#8203;TYPE_&#8203;QUALIFIER</code> if the argument is declared with the

<p><code>CL_&#8203;KERNEL_&#8203;ARG_&#8203;TYPE_&#8203;VOLATILE</code> is returned for
<code>CL_&#8203;KERNEL_&#8203;ARG_&#8203;TYPE_&#8203;QUALIFIER</code> if the argument is a pointer and the
referenced type is declared with the volatile qualifier.
For example, a kernel argument declared as <code>global int volatile *x</code>
returns <code>CL_&#8203;KERNEL_&#8203;ARG_&#8203;TYPE_&#8203;VOLATILE</code> but a kernel argument declared
as <code>global int * volatile x</code> does not.
Similarly, <code>CL_&#8203;KERNEL_&#8203;ARG_&#8203;TYPE_&#8203;CONST</code> is returned if the argument is a
pointer and the referenced type is declared with the restrict or
const qualifier.
For example, a kernel argument declared as <code>global int const *x</code>
returns <code>CL_&#8203;KERNEL_&#8203;ARG_&#8203;TYPE_&#8203;CONST</code> but a kernel argument declared as
<code>global int * const x</code> does not.
<code>CL_&#8203;KERNEL_&#8203;ARG_&#8203;TYPE_&#8203;RESTRICT</code> will be returned if the pointer type is
marked <code>restrict</code>.
For example, <code>global int * restrict x</code> returns
<code>CL_&#8203;KERNEL_&#8203;ARG_&#8203;TYPE_&#8203;RESTRICT</code>.</p>
