9 | <code class="function">glGenSamplers</code> returns <em class="parameter"><code>n</code></em> sampler object names in <em class="parameter"><code>samplers</code></em>. | |
10 | There is no guarantee that the names form a contiguous set of integers; however, it is guaranteed that none of the returned names | |
11 | was in use immediately before the call to <code class="function">glGenSamplers</code>. | |
12 | </p><p> | |
13 | Sampler object names returned by a call to <code class="function">glGenSamplers</code> are not returned by subsequent calls, unless | |
14 | they are first deleted with <a href="glDeleteSamplers.xml"><span class="citerefentry"><span class="refentrytitle">glDeleteSamplers</span></span></a>. | |
15 | </p><p> | |
16 | 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, | |
17 | but they acquire state and type only when they are first bound. | |
18 | </p></div><div class="refsect1" lang="en" xml:lang="en"><a id="notes"></a><h2>Notes</h2><p> | |
