        <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>glMapBufferRange</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>.

            Calling <function>glBindBufferBase</function> binds the entire buffer, even when the size of the buffer is
                        changed after the binding is established. The starting offset is zero, and the amount
                        of data that can be read from or written to the buffer is determined by the size of
                        the bound buffer at the time the binding is used.
