<h2>Description</h2>
<p><code class="function">glGetAttachedShaders</code> returns the
names of the shader objects attached to
<em class="parameter"><code>program</code></em>. The names of shader objects that
are attached to <em class="parameter"><code>program</code></em> will be returned
in <em class="parameter"><code>shaders.</code></em> The actual number of shader
names written into <em class="parameter"><code>shaders</code></em> is returned in
<em class="parameter"><code>count.</code></em> If no shader objects are attached
to <em class="parameter"><code>program</code></em>, <em class="parameter"><code>count</code></em>
is set to 0. The maximum number of shader names that may be
returned in <em class="parameter"><code>shaders</code></em> is specified by
<em class="parameter"><code>maxCount</code></em>. </p>
<p>If the number of names actually returned is not required
(for instance, if it has just been obtained by calling
<a class="citerefentry" href="glGetProgram.xhtml"><span class="citerefentry"><span class="refentrytitle">glGetProgram</span></span></a>),
a value of <code class="constant">NULL</code> may be passed for count. If
no shader objects are attached to
<em class="parameter"><code>program</code></em>, a value of 0 will be returned in
<em class="parameter"><code>count</code></em>. The actual number of attached
shaders can be obtained by calling
<a class="citerefentry" href="glGetProgram.xhtml"><span class="citerefentry"><span class="refentrytitle">glGetProgram</span></span></a>
with the value <code class="constant">GL_ATTACHED_SHADERS</code>.</p>

<h2>Errors</h2>
<p><code class="constant">GL_INVALID_VALUE</code> is generated if

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>
