<h2>Description</h2>

<p>

<code class="function">glDeleteTextures</code> deletes <em class="parameter"><code>n</code></em> textures named by the elements of the array <em class="parameter"><code>textures</code></em>.

After a texture is deleted, it has no contents or dimensionality,

and its name is again unused.

If a texture that is currently bound is deleted, the binding reverts

to 0 (the default texture).

</p>

<p>

Unused names in <em class="parameter"><code>textures</code></em> that have been marked as used for the purposes of

<a class="citerefentry" href="glGenTextures"><span class="citerefentry"><span class="refentrytitle">glGenTextures</span></span></a> are marked as unused again.

<code class="function">glDeleteTextures</code> silently ignores 0's and names that do not correspond to

existing textures.

</p>

</div>

<div class="refsect1" id="errors">

<h2>Errors</h2>

<p>

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