<h2>Description</h2>

<p>

<code class="function">glBindBufferBase</code> binds the buffer object <em class="parameter"><code>buffer</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"><span class="citerefentry"><span class="refentrytitle">glBindBuffer</span></span></a>

or <a class="citerefentry" href="glMapBufferRange"><span class="citerefentry"><span class="refentrytitle">glMapBufferRange</span></span></a>. In addition to binding

<em class="parameter"><code>buffer</code></em> to the indexed buffer binding target, <code class="function">glBindBufferBase</code>

also binds <em class="parameter"><code>buffer</code></em> to the generic buffer binding point specified by <em class="parameter"><code>target</code></em>.

</p>

</div>

<div class="refsect1" id="notes">

<h2>Notes</h2>

<p>

Calling <code class="function">glBindBufferBase</code> 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.

</p>

<p>

The <code class="constant">GL_ATOMIC_COUNTER_BUFFER</code> and <code class="constant">GL_SHADER_STORAGE_BUFFER</code>

targets are available only if the GL ES version is 3.1 or greater.

</p>

</div>

<div class="refsect1" id="errors">

<h2>Errors</h2>

<p>

<code class="constant">GL_INVALID_ENUM</code> is generated if <em class="parameter"><code>target</code></em> is not

<code class="constant">GL_ATOMIC_COUNTER_BUFFER</code>, <code class="constant">GL_SHADER_STORAGE_BUFFER</code>,

<code class="constant">GL_TRANSFORM_FEEDBACK_BUFFER</code> or <code class="constant">GL_UNIFORM_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.
