        <para>
            <function>glBindBufferBase</function> binds the buffer object <parameter>buffer</parameter>
            to the binding point at index <parameter>index</parameter> of the array of targets specified
            by <parameter>target</parameter>. Each <parameter>target</parameter> represents an indexed
            array of buffer binding points, as well as a single general binding point that can be used by
            other buffer manipulation functions such as <citerefentry><refentrytitle>glBindBuffer</refentrytitle></citerefentry>
            or <citerefentry><refentrytitle>glMapBuffer</refentrytitle></citerefentry>. In addition to binding
            <parameter>buffer</parameter> to the indexed buffer binding target, <function>glBindBufferBase</function>
            also binds <parameter>buffer</parameter> to the generic buffer binding point specified by <parameter>target</parameter>.

            zero and <parameter>size</parameter> equal to the size of the buffer.
