<h2>Description</h2>
<p>
<code class="function">glShaderBinary</code> loads pre-compiled shader binary code into the <em class="parameter"><code>count</code></em>
shader objects whose handles are given in <em class="parameter"><code>shaders</code></em>. <em class="parameter"><code>binary</code></em>
points to <em class="parameter"><code>length</code></em> bytes of binary shader code stored in client memory.
<em class="parameter"><code>binaryFormat</code></em> specifies the format of the pre-compiled code.
</p>
<p>
The binary image contained in <em class="parameter"><code>binary</code></em> will be decoded according to the extension
specification defining the specified <em class="parameter"><code>binaryFormat</code></em> token. OpenGL
does not define any specific binary formats, but it does provide a mechanism to obtain token
vaues for such formats provided by such extensions.
</p>
<p>
Depending on the types of the shader objects in <em class="parameter"><code>shaders</code></em>, <code class="function">glShaderBinary</code>
will individually load binary vertex or fragment shaders, or load an executable binary that contains an optimized
pair of vertex and fragment shaders stored in the same binary.
</p>
</div>
<div class="refsect1" id="errors">
<h2>Errors</h2>
<p>
<code class="constant">GL_INVALID_OPERATION</code> is generated if more than one of the handles in
<em class="parameter"><code>shaders</code></em> refers to the same shader object.
</p>
<p>
<code class="constant">GL_INVALID_ENUM</code> is generated if <em class="parameter"><code>binaryFormat</code></em> is not an
accepted value.
</p>
<p>
<code class="constant">GL_INVALID_VALUE</code> is generated if the data pointed to by <em class="parameter"><code>binary</code></em>
does not match the format specified by <em class="parameter"><code>binaryFormat</code></em>.
