<h2>Description</h2>
<p>
<code class="function">glBindVertexBuffers</code> and
<code class="function">glVertexArrayVertexBuffers</code> bind storage
from an array of existing buffer objects to a specified number
of consecutive vertex buffer binding points units in a vertex
array object. For <code class="function">glBindVertexBuffers</code>, the
vertex array object is the currently bound vertex array object.
For <code class="function">glVertexArrayVertexBuffers</code>,
<em class="parameter"><code>vaobj</code></em> is the name of the vertex array
object.
</p>
<p>
<em class="parameter"><code>count</code></em> existing buffer objects are bound
to vertex buffer binding points numbered $first$ through $first
+ count - 1$. If <em class="parameter"><code>buffers</code></em> is not NULL, it
specifies an array of <em class="parameter"><code>count</code></em> values, each
of which must be zero or the name of an existing buffer object.
<em class="parameter"><code>offsets</code></em> and
<em class="parameter"><code>strides</code></em> specify arrays of
<em class="parameter"><code>count</code></em> values indicating the offset of the
first element and stride between elements in each buffer,
respectively. If <em class="parameter"><code>buffers</code></em> is NULL, each
affected vertex buffer binding point from $first$ through $first
+ count - 1$ will be reset to have no bound buffer object. In
this case, the offsets and strides associated with the binding
points are set to default values, ignoring
<em class="parameter"><code>offsets</code></em> and
<em class="parameter"><code>strides</code></em>.
</p>
<p>
<code class="function">glBindVertexBuffers</code> is equivalent (assuming no errors
are generated) to:
</p>
<pre class="programlisting"> for (i = 0; i < count; i++) {
if (buffers == NULL) {
glBindVertexBuffer(first + i, 0, 0, 16);
} else {
glBindVertexBuffer(first + i, buffers[i], offsets[i], strides[i]);
}
}</pre>
<p>
except that buffers will not be created if they do not exist.
</p>
<p>
<code class="function">glVertexArrayVertexBuffers</code> is equivalent to
the pseudocode above, but replacing
<code class="function">glBindVertexBuffers</code>(args) with
<code class="function">glVertexArrayVertexBuffers</code>(vaobj, args).
</p>
<p>
The values specified in <em class="parameter"><code>buffers</code></em>,
<em class="parameter"><code>offsets</code></em>, and
<em class="parameter"><code>strides</code></em> will be checked separately for
each vertex buffer binding point. When a value for a specific
vertex buffer binding point is invalid, the state for that
binding point will be unchanged and an error will be generated.
However, state for other vertex buffer binding points will still
be changed if their corresponding values are valid.
</p>
</div>
<div class="refsect1" id="errors">
<h2>Errors</h2>
<p>
<code class="constant">GL_INVALID_OPERATION</code> is generated
by <code class="function">glBindVertexBuffers</code> if no vertex array
object is bound.
</p>
<p>
<code class="constant">GL_INVALID_OPERATION</code> is generated by
<code class="function">glVertexArrayVertexBuffers</code> if
<em class="parameter"><code>vaobj</code></em> is not the name of the vertex array
object.
</p>
<p>
<code class="constant">GL_INVALID_OPERATION</code> is generated if $first
+ count$ is greater than the value of
<code class="constant">GL_MAX_VERTEX_ATTRIB_BINDINGS</code>.
</p>
<p>
<code class="constant">GL_INVALID_OPERATION</code> is generated if any
value in <code class="constant">buffers</code> is not zero or the name of
an existing buffer object.
</p>
<p>
<code class="constant">GL_INVALID_VALUE</code> is generated if any value
in <em class="parameter"><code>offsets</code></em> or
<em class="parameter"><code>strides</code></em> is negative, or if a value is
<em class="parameter"><code>stride</code></em> is greater than the value of
<code class="constant">GL_MAX_VERTEX_ATTRIB_STRIDE</code>.
