<h2>Description</h2>

<p>

<code class="function">glGenSamplers</code> returns <em class="parameter"><code>n</code></em> sampler object names in <em class="parameter"><code>samplers</code></em>.

There is no guarantee that the names form a contiguous set of integers; however, it is guaranteed that none of the returned names

was in use immediately before the call to <code class="function">glGenSamplers</code>.

</p>

<p>

Sampler object names returned by a call to <code class="function">glGenSamplers</code> are not returned by subsequent calls, unless

they are first deleted with <a class="citerefentry" href="glDeleteSamplers"><span class="citerefentry"><span class="refentrytitle">glDeleteSamplers</span></span></a>.

</p>

<p>

The names returned in <em class="parameter"><code>samplers</code></em> are marked as used, for the purposes of <code class="function">glGenSamplers</code> only,

but they acquire state and type only when they are first used as a parameter to

<a class="citerefentry" href="glBindSampler"><span class="citerefentry"><span class="refentrytitle">glBindSampler</span></span></a>,

<a class="citerefentry" href="glSamplerParameter"><span class="citerefentry"><span class="refentrytitle">glSamplerParameter</span></span></a>*,

<a class="citerefentry" href="glGetSamplerParameter"><span class="citerefentry"><span class="refentrytitle">glGetSamplerParameter</span></span></a>* or

<a class="citerefentry" href="glIsSampler"><span class="citerefentry"><span class="refentrytitle">glIsSampler</span></span></a>.

<h2>Errors</h2>

<code class="constant">GL_INVALID_VALUE</code> is generated if <em class="parameter"><code>n</code></em> is negative.
