41 <function>glIsVertexArray
</function> returns
<constant>GL_TRUE
</constant> if
<parameter>array
</parameter> is currently the name of a renderbuffer
42 object. If
<parameter>renderbuffer
</parameter> is zero, or if
<parameter>array
</parameter> is not the name of a renderbuffer object, or if an error
43 occurs,
<function>glIsVertexArray
</function> returns
<constant>GL_FALSE
</constant>. If
<parameter>array
</parameter> is a name returned by

</refentrytitle></citerefentry>, by that has not yet been bound through a call to
45 <citerefentry><refentrytitle>glBindVertexArray
</refentrytitle></citerefentry>, then the name is not a vertex array object and
46 <function>glIsVertexArray
</function> returns
<constant>GL_FALSE
