<h2>Description</h2>

<p><code class="function">glDetachShader</code> detaches the shader

object specified by <em class="parameter"><code>shader</code></em> from the

program object specified by <em class="parameter"><code>program</code></em>. This

command can be used to undo the effect of the command

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

<p>If <em class="parameter"><code>shader</code></em> has already been flagged

for deletion by a call to

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

and it is not attached to any other program object, it will be

deleted after it has been detached.</p>

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

<h2>Errors</h2>

<p><code class="constant">GL_INVALID_VALUE</code> is generated if either

<em class="parameter"><code>program</code></em> or <em class="parameter"><code>shader</code></em>

is a value that was not generated by OpenGL.</p>

<p><code class="constant">GL_INVALID_OPERATION</code> is generated if

<em class="parameter"><code>program</code></em> is not a program object.</p>
