        <para>
            <function>glBindBufferRange</function> binds a range the buffer object <parameter>buffer</parameter>
            represented by <parameter>offset</parameter> and <parameter>size</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
            a range of <parameter>buffer</parameter> to the indexed buffer binding target, <function>glBindBufferRange</function>
            also binds the range to the generic buffer binding point specified by <parameter>target</parameter>.
        </para>
        <para>
            <parameter>offset</parameter> specifies the offset in basic machine units into the buffer object
            <parameter>buffer</parameter> and <parameter>size</parameter> specifies the amount of data that
            can be read from the buffer object while used as an indexed target.

            The <constant>GL_ATOMIC_COUNTER_BUFER</constant> target is available only if the GL version is 4.2 or greater.

            The <constant>GL_SHADER_STORAGE_BUFFER</constant> target is available only if the GL version is 4.3 or greater.

        <para>
            <constant>GL_INVALID_VALUE</constant> is generated if <parameter>size</parameter> is less than
