    <para><function>glGetVertexAttribPointerv</function> returns
    pointer information. <parameter>index</parameter> is the generic
    vertex attribute to be queried, <parameter>pname</parameter> is
    a symbolic constant indicating the pointer to be returned, and
    <parameter>params</parameter> is a pointer to a location in
    which to place the returned data.</para>

    <para>The <parameter>pointer</parameter> returned is a byte offset into the data store of the buffer object
    that was bound to the <constant>GL_ARRAY_BUFFER</constant> target
    (see <citerefentry><refentrytitle>glBindBuffer</refentrytitle></citerefentry>) when the desired pointer was previously specified.

    <para>The state returned is retrieved from the currently bound vertex array object. If the zero object is bound,
