<code class="function">glBindBufferRange</code> binds a range the buffer object <em class="parameter"><code>buffer</code></em>
represented by <em class="parameter"><code>offset</code></em> and <em class="parameter"><code>size</code></em> to the
binding point at index <em class="parameter"><code>index</code></em> of the array of targets specified by <em class="parameter"><code>target</code></em>.
Each <em class="parameter"><code>target</code></em> 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
<a class="citerefentry" href="glBindBuffer.xml"><span class="citerefentry"><span class="refentrytitle">glBindBuffer</span></span></a> or
<a class="citerefentry" href="glMapBuffer.xml"><span class="citerefentry"><span class="refentrytitle">glMapBuffer</span></span></a>. In addition to binding
a range of <em class="parameter"><code>buffer</code></em> to the indexed buffer binding target, <code class="function">glBindBufferRange</code>
also binds the range to the generic buffer binding point specified by <em class="parameter"><code>target</code></em>.
</p><p>
<em class="parameter"><code>offset</code></em> specifies the offset in basic machine units into the buffer object
<em class="parameter"><code>buffer</code></em> and <em class="parameter"><code>size</code></em> specifies the amount of data that
can be read from the buffer object while used as an indexed target.
</p></div><div class="refsect1"><a id="notes"></a><h2>Notes</h2><p>
The <code class="constant">GL_ATOMIC_COUNTER_BUFFER</code> target is available only if the GL version is 4.2 or greater.
</p><p>
The <code class="constant">GL_SHADER_STORAGE_BUFFER</code> target is available only if the GL version is 4.3 or greater.
</p></div><div class="refsect1"><a id="errors"></a><h2>Errors</h2><p>
<code class="constant">GL_INVALID_ENUM</code> is generated if <em class="parameter"><code>target</code></em> is not
one of <code class="constant">GL_ATOMIC_COUNTER_BUFFER</code>,
<code class="constant">GL_TRANSFORM_FEEDBACK_BUFFER</code>, <code class="constant">GL_UNIFORM_BUFFER</code> or
<code class="constant">GL_SHADER_STORAGE_BUFFER</code>.
</p><p>
<code class="constant">GL_INVALID_VALUE</code> is generated if <em class="parameter"><code>index</code></em> is greater
than or equal to the number of <em class="parameter"><code>target</code></em>-specific indexed binding points.
</p><p>
<code class="constant">GL_INVALID_VALUE</code> is generated if <em class="parameter"><code>size</code></em> is less than
or equal to zero, or if <em class="parameter"><code>offset</code></em> + <em class="parameter"><code>size</code></em> is greater
than the value of <code class="constant">GL_BUFFER_SIZE</code>.
</p><p>
Additional errors may be generated if <em class="parameter"><code>offset</code></em> violates any
<em class="parameter"><code>target</code></em>-specific alignmemt restrictions.
