13 <code class=

</code> is equivalent to calling
14 <a href=
"glRenderbufferStorageMultisample.xml"><span class=
"citerefentry"><span class=
"refentrytitle">glRenderbufferStorageMultisample
</span></span></a> with the
15 <em class=
"parameter"><code>samples
</code></em> set to zero.
17 The target of the operation, specified by
<em class=
"parameter"><code>target
</code></em> must be
<code class=
"constant">GL_RENDERBUFFER
</code>.
18 <em class=
"parameter"><code>internalformat
</code></em> specifies the internal format to be used for the renderbuffer object's storage and
19 must be a color-renderable, depth-renderable, or stencil-renderable format.
20 <em class=
"parameter"><code>width
</code></em> and
<em class=
"parameter"><code>height
</code></em> are the dimensions, in pixels, of the renderbuffer.
21 Both
<em class=
"parameter"><code>width
</code></em> and
<em class=
"parameter"><code>height
</code></em> must be less than or equal to the value of
22 <code class=
"constant">GL_MAX_RENDERBUFFER_SIZE
</code>.
24 Upon success,
<code class=
"function">glRenderbufferStorage
</code> deletes any existing data store for the renderbuffer
25 image and the contents of the data store after calling
<code class=
"function">glRenderbufferStorage
</code> are undefined.

29 <code class=
