<h2>Description</h2>

<p>

<code class="function">glBindSampler</code> binds <em class="parameter"><code>sampler</code></em> to the texture unit at index <em class="parameter"><code>unit</code></em>.

<em class="parameter"><code>sampler</code></em> must be zero or the name of a sampler object previously returned from a call to

<a class="citerefentry" href="glGenSamplers"><span class="citerefentry"><span class="refentrytitle">glGenSamplers</span></span></a>. <em class="parameter"><code>unit</code></em> must be less than the value

of <code class="constant">GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS</code>.

</p>

<p>

When a sampler object is bound to a texture unit, its state supersedes that of

the texture object bound to that texture unit. If the sampler name zero is bound to

a texture unit, the currently bound texture's sampler state becomes active. A single

sampler object may be bound to multiple texture units simultaneously.

<h2>Errors</h2>

<p>

<code class="constant">GL_INVALID_VALUE</code> is generated if <em class="parameter"><code>unit</code></em> is greater than or equal to the value of

<code class="constant">GL_MAX_COMBIED_TEXTURE_IMAGE_UNITS</code>.

</p>

<p>

<code class="constant">GL_INVALID_OPERATION</code> is generated if <em class="parameter"><code>sampler</code></em> is not zero or a name previously

returned from a call to <a class="citerefentry" href="glGenSamplers"><span class="citerefentry"><span class="refentrytitle">glGenSamplers</span></span></a>, or if such a name has

been deleted by a call to <a class="citerefentry" href="glDeleteSamplers"><span class="citerefentry"><span class="refentrytitle">glDeleteSamplers</span></span></a>.
