<h2>Description</h2>
<p>
Returns the number of local work-items specified in dimension
identified by <code class="varname">dimindx</code>. This value
is at most the value given by the <code class="varname">local_work_size</code> argument to
<a class="citerefentry" href="clEnqueueNDRangeKernel.html"><span class="citerefentry"><span class="refentrytitle">clEnqueueNDRangeKernel</span></span></a> if
<code class="varname">local_work_size</code> is not NULL; otherwise the OpenCL implementation
chooses an appropriate <code class="varname">local_work_size</code> value which is
returned by this function.
If the kernel is executed with a nonuniform work-group size
(i.e. the <code class="varname">global_work_size</code> values specified to
<a class="citerefentry" href="clEnqueueNDRangeKernel.html"><span class="citerefentry"><span class="refentrytitle">clEnqueueNDRangeKernel</span></span></a>
are not evenly divisable by the
<code class="varname">local_work_size</code> values for each dimension),
calls to this built-in from
some work-groups may return different values than calls
to this built-in from other work-groups.
</p>
<p>
Valid values of <code class="varname">dimindx</code> are 0 to
<a class="citerefentry" href="get_work_dim.html"><span class="citerefentry"><span class="refentrytitle">get_work_dim</span></span></a>() - 1. For other
values of <code class="varname">dimindx</code>, <code class="function">get_local_size</code>() returns 1.
