            object. If <parameter>renderbuffer</parameter> is zero, or if <parameter>renderbuffer</parameter> is not the name of a renderbuffer object, or if an error
            occurs, <function>glIsRenderbuffer</function> returns <constant>GL_FALSE</constant>. If <parameter>renderbuffer</parameter> is a name returned by
