<h2>Description</h2>
<p>
<code class="function">glFramebufferRenderbuffer</code> and
<code class="function">glNamedFramebufferRenderbuffer</code> attaches a
renderbuffer as one of the logical buffers of the specified
framebuffer object. Renderbuffers cannot be attached to the
default draw and read framebuffer, so they are not valid targets
of these commands.
</p>
<p>
For <code class="function">glFramebufferRenderbuffer</code>,
the framebuffer object is that bound to
<em class="parameter"><code>target</code></em>, which must be
<code class="constant">GL_DRAW_FRAMEBUFFER</code>,
<code class="constant">GL_READ_FRAMEBUFFER</code> or
<code class="constant">GL_FRAMEBUFFER</code>.
<code class="constant">GL_FRAMEBUFFER</code> is equivalent to
<code class="constant">GL_DRAW_FRAMEBUFFER</code>.
</p>
<p>
For <code class="function">glNamedFramebufferRenderbuffer</code>,
<em class="parameter"><code>framebuffer</code></em> is the name of the
framebuffer object.
</p>
<p>
<em class="parameter"><code>renderbuffertarget</code></em> must be
<code class="constant">GL_RENDERBUFFER</code>.
</p>
<p>
<em class="parameter"><code>renderbuffer</code></em> must be zero or the name of
an existing renderbuffer object of type
<em class="parameter"><code>renderbuffertarget</code></em>. If
<em class="parameter"><code>renderbuffer</code></em> is not zero, then the
specified renderbuffer will be used as the logical buffer
identified by <em class="parameter"><code>attachment</code></em> of the specified
framebuffer object. If <em class="parameter"><code>renderbuffer</code></em> is
zero, then the value of
<em class="parameter"><code>renderbuffertarget</code></em> is ignored.
</p>
<p>
<em class="parameter"><code>attachment</code></em> specifies the logical
attachment of the framebuffer and must be
<code class="constant">GL_COLOR_ATTACHMENT</code><span class="emphasis"><em>i</em></span>,
<code class="constant">GL_DEPTH_ATTACHMENT</code>,
<code class="constant">GL_STENCIL_ATTACHMENT</code> or
<code class="constant">GL_DEPTH_STENCIL_ATTACHMENT</code>.
<span class="emphasis"><em>i</em></span> in may range from zero to the value of
<code class="constant">GL_MAX_COLOR_ATTACHMENTS</code> minus one.
Setting <em class="parameter"><code>attachment</code></em> to the value
<code class="constant">GL_DEPTH_STENCIL_ATTACHMENT</code> is a special
case causing both the depth and stencil attachments of the
specified framebuffer object to be set to
<em class="parameter"><code>renderbuffer</code></em>, which should have the base
internal format <code class="constant">GL_DEPTH_STENCIL</code>.
</p>
<p>
The value of
<code class="constant">GL_FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE</code> for
the specified attachment point is set to
<code class="constant">GL_RENDERBUFFER</code> and the value of
<code class="constant">GL_FRAMEBUFFER_ATTACHMENT_OBJECT_NAME</code> is
set to <em class="parameter"><code>renderbuffer</code></em>. All other state
values of specified attachment point are set to their default
values. No change is made to the state of the renderbuuffer
object and any previous attachment to the
<em class="parameter"><code>attachment</code></em> logical buffer of the
specified framebuffer object is broken.
</p>
<p>
If <em class="parameter"><code>renderbuffer</code></em> is zero, these commands
will detach the image, if any, identified by the specified
attachment point of the specified framebuffer object. All state
values of the attachment point are set to their default values.
</p>
</div>
<div class="refsect1" id="errors">
<h2>Errors</h2>
<p>
<code class="constant">GL_INVALID_ENUM</code> is generated by
<code class="function">glFramebufferRenderbuffer</code> if
<em class="parameter"><code>target</code></em> is not one of the accepted
framebuffer targets.
</p>
<p>
<code class="constant">GL_INVALID_OPERATION</code> is generated by
<code class="function">glFramebufferRenderbuffer</code> if zero is bound
to <em class="parameter"><code>target</code></em>.
</p>
<p>
<code class="constant">GL_INVALID_OPERATION</code> is generated by
<code class="function">glNamedFramebufferRenderbuffer</code> if
<em class="parameter"><code>framebuffer</code></em> is not the name of an
existing framebuffer object.
</p>
<p>
<code class="constant">GL_INVALID_ENUM</code> is generated if
<em class="parameter"><code>attachment</code></em> is not one of the accepted
attachment points.
</p>
<p>
<code class="constant">GL_INVALID_ENUM</code> is generated if
<em class="parameter"><code>renderbuffertarget</code></em> is not
<code class="constant">GL_RENDERBUFFER</code>.
</p>
<p>
<code class="constant">GL_INVALID_OPERATION</code> is generated if
<em class="parameter"><code>renderbuffertarget</code></em> is not zero or the
name of an existing renderbuffer object of type
<code class="constant">GL_RENDERBUFFER</code>.
