47<h2>Return Values</h2>
48<div class="section">No values are returned. </div>
49<h2>Description</h2>
50    <div class="section">
51<p>Gets vertex attribute parameters as <code>GLfloat</code>-type values.</p><P>
52Set <span class="argument">index</span> to a value that is greater than or equal to 0 and at least one less than the value that can be obtained by <code>glGetIntegerv</code> with <code>GL_MAX_VERTEX_ATTRIBS</code> specified.
53            </P><P>
54If you set <code>pname</code> to <code>GL_CURRENT_VERTEX_ATTRIB</code>, you can get the current vertex attribute values, set by <code>glVertexAttrib</code>, as four array elements.
55            </P><P>
56You can also set <code>pname</code> to any setting that can be obtained by <code>glGetVertexAttribiv</code>, but you will get values that have all been cast to type <code>GLfloat</code>.
