<h2>Description</h2>
<p>
<code class="function">glBindSamplers</code> binds samplers from an array of existing sampler objects to a specified
number of consecutive sampler units. <em class="parameter"><code>count</code></em> specifies the number of sampler
objects whose names are stored in the array <em class="parameter"><code>samplers</code></em>. That number
of sampler names is read from the array and bound to the <em class="parameter"><code>count</code></em> consecutive
sampler units starting from <em class="parameter"><code>first</code></em>.
</p>
<p>
If the name zero appears in the <em class="parameter"><code>samplers</code></em> array, any existing binding
to the sampler unit is reset. Any non-zero entry in <em class="parameter"><code>samplers</code></em> must be the
name of an existing sampler object. When a non-zero entry in <em class="parameter"><code>samplers</code></em> is
present, that sampler object is bound to the corresponding sampler unit.
If <em class="parameter"><code>samplers</code></em> is <code class="constant">NULL</code> then it is as
if an appropriately sized array containing only zeros had been specified.
</p>
<p>
<code class="function">glBindSamplers</code> is equivalent to the following pseudo code:
</p>
<pre class="programlisting"> for (i = 0; i < count; i++) {
if (samplers == NULL) {
glBindSampler(first + i, 0);
} else {
glBindSampler(first + i, samplers[i]);
}
}</pre>
<p>
Each entry in <em class="parameter"><code>samplers</code></em> will be checked individually and if found
to be invalid, the state for that sampler unit will not be changed and an error will be
generated. However, the state for other sampler units referenced by the command will still
be updated.
</p>
</div>
<div class="refsect1" id="notes">
<h2>Notes</h2>
<p>
<code class="function">glBindSamplers</code> is available only if the GL version is 4.4 or higher.
</p>
</div>
<div class="refsect1" id="errors">
<h2>Errors</h2>
<p>
<code class="constant">GL_INVALID_OPERATION</code> is generated if <em class="parameter"><code>first</code></em> + <em class="parameter"><code>count</code></em> is greater
than the number of sampler units supported by the implementation.
</p>
<p>
<code class="constant">GL_INVALID_OPERATION</code> is generated if any value in <em class="parameter"><code>samplers</code></em> is
not zero or the name of an existing sampler object.
