<para>
<function>glRenderbufferStorage</function> is equivalent to calling
<citerefentry><refentrytitle>glRenderbufferStorageMultisample</refentrytitle></citerefentry> with the
<parameter>samples</parameter> set to zero.
</para>
<para>
The target of the operation, specified by <parameter>target</parameter> must be <constant>GL_RENDERBUFFER</constant>.
<parameter>internalformat</parameter> specifies the internal format to be used for the renderbuffer object's storage and
must be a color-renderable, depth-renderable, or stencil-renderable format.
<parameter>width</parameter> and <parameter>height</parameter> are the dimensions, in pixels, of the renderbuffer.
Both <parameter>width</parameter> and <parameter>height</parameter> must be less than or equal to the value of
<constant>GL_MAX_RENDERBUFFER_SIZE</constant>.
</para>
<para>
Upon success, <function>glRenderbufferStorage</function> deletes any existing data store for the renderbuffer
image and the contents of the data store after calling <function>glRenderbufferStorage</function> are undefined.

<para>
<constant>GL_INVALID_VALUE</constant> is generated if either of <parameter>width</parameter> or <parameter>height</parameter> is negative,
or greater than the value of <constant>GL_MAX_RENDERBUFFER_SIZE</constant>.
</para>
<para>
<constant>GL_INVALID_ENUM</constant> is generated if <parameter>internalformat</parameter> is not a color-renderable, depth-renderable,
or stencil-renderable format.
</para>
<para>
<constant>GL_OUT_OF_MEMORY</constant> is generated if the GL is unable to create a data store of the requested size.
