<h2>Description</h2>

<p><code class="function">glDeleteShader</code> frees the memory and

invalidates the name associated with the shader object specified

by <em class="parameter"><code>shader</code></em>. This command effectively

undoes the effects of a call to

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

<p>If a shader object to be deleted is attached to a program

object, it will be flagged for deletion, but it will not be

deleted until it is no longer attached to any program object,

for any rendering context (i.e., it must be detached from

wherever it was attached before it will be deleted). A value of

0 for <em class="parameter"><code>shader</code></em> will be silently

ignored.</p>

<p>To determine whether an object has been flagged for

deletion, call

<a class="citerefentry" href="glGetShaderiv"><span class="citerefentry"><span class="refentrytitle">glGetShaderiv</span></span></a>

with arguments <em class="parameter"><code>shader</code></em> and

<code class="constant">GL_DELETE_STATUS</code>.</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>shader</code></em> is not a value generated by

OpenGL.</p>
