</h2><p>
16 <code class=
"function">glBindBufferRange
</code> binds a range the buffer object
<em class=
"parameter"><code>buffer
</code></em>
17 represented by
<em class=
"parameter"><code>offset
</code></em> and
<em class=
"parameter"><code>size
</code></em> to the
18 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>.
19 Each
<em class=
"parameter"><code>target
</code></em> represents an indexed array of buffer binding points, as well
20 as a single general binding point that can be used by other buffer manipulation functions such as
21 <a href=
"glBindBuffer.xml"><span class=
"citerefentry"><span class=
"refentrytitle">glBindBuffer
</span></span></a> or
22 <a href=
"glMapBuffer.xml"><span class=
"citerefentry"><span class=
"refentrytitle">glMapBuffer
</span></span></a>. In addition to binding
23 a range of
<em class=
"parameter"><code>buffer
</code></em> to the indexed buffer binding target,
<code class=
"function">glBindBufferRange
</code>
24 also binds the range to the generic buffer binding point specified by
<em class=
"parameter"><code>target
</code></em>.
26 <em class=
"parameter"><code>offset
</code></em> specifies the offset in basic machine units into the buffer object
27 <em class=
"parameter"><code>buffer
</code></em> and
<em class=
"parameter"><code>size
</code></em> specifies the amount of data that
28 can be read from the buffer object while used as an indexed target.
