<title>Description</title>
<para><function>glBindVertexBuffer</function> and
<function>glVertexArrayVertexBuffer</function> bind the buffer named
<parameter>buffer</parameter> to the vertex buffer binding point whose
index is given by <parameter>bindingindex</parameter>.
<function>glBindVertexBuffer</function> modifies the binding of the
currently bound vertex array object, whereas
<function>glVertexArrayVertexBuffer</function> allows the caller to
specify ID of the vertex array object with an argument named
<parameter>vaobj</parameter>, for which the binding should be modified.
<parameter>offset</parameter> and <parameter>stride</parameter> specify
the offset of the first element within the buffer and the distance between
elements within the buffer, respectively, and are both measured in basic
machine units. <parameter>bindingindex</parameter> must be less than the
value of <constant>GL_MAX_VERTEX_ATTRIB_BINDINGS</constant>.
<parameter>offset</parameter> and <parameter>stride</parameter> must be
greater than or equal to zero. If <parameter>buffer</parameter> is zero,
then any buffer currently bound to the specified binding point is
unbound.</para>
<para>If <parameter>buffer</parameter> is not the name of an existing
buffer object, the GL first creates a new state vector, initialized with a
zero-sized memory buffer and comprising all the state and with the same
initial values as in case of <function>glBindBuffer</function>.
<parameter>buffer</parameter> is then attached to the specified
<parameter>bindingindex</parameter> of the vertex array object.</para>
