<title>Description</title>
<para>This function provides a mean of querying properties of an existing
vertex array object. The vertex array object does not have to be bound to
the rendering context at the time of the call, but must have been bound at
least once prior to this call.</para>
<para><function>glGetVertexArrayiv</function> can be used to retrieve ID
of a buffer object that will be bound to the
<constant>GL_ELEMENT_ARRAY_BUFFER</constant> binding point whenever the
queried vertex array object is bound to the rendering context. The binding
can be changed for an active vertex array object with a
<function>glBindBuffer</function> call.</para>
