<function>glSampleMaski</function> sets one 32-bit sub-word of the multi-word sample mask, <constant>GL_SAMPLE_MASK_VALUE</constant>.
</para>
<para>
<parameter>maskIndex</parameter> specifies which 32-bit sub-word of the sample mask to update, and <parameter>mask</parameter> specifies
the new value to use for that sub-word. <parameter>maskIndex</parameter> must be less than the value of
<constant>GL_MAX_SAMPLE_MASK_WORDS</constant>. Bit <emphasis>B</emphasis> of mask word <emphasis>M</emphasis> corresponds to sample
32 x <emphasis>M</emphasis> + <emphasis>B</emphasis>.

<function>glSampleMaski</function> is available only if the GL version is 3.2 or greater, or if the <code>ARB_texture_multisample</code>
extension is supported.
