<para>
<function>glTexBufferRange</function> attaches the a range of the data store of the buffer object named <parameter>buffer</parameter> to the active
buffer texture, and specifies the internal format for the texel array found in the attached buffer object. If <parameter>buffer</parameter>
is zero, any buffer object attached to the buffer texture is detached and no new buffer object is attached. If <parameter>buffer</parameter>
is non-zero, it must be the name of an existing buffer object. <parameter>target</parameter> must be <constant>GL_TEXTURE_BUFFER</constant>.
The start of the range is specified by <parameter>offset</parameter> and the size of the range is specified by <parameter>size</parameter>,
both measured in basic machine units. <parameter>offset</parameter> must be greater than or equal to zero, <parameter>size</parameter> must be greater
than zero, and the sum of <parameter>offset</parameter> and <parameter>size</parameter> not exceed the value
of <constant>GL_BUFFER_SIZE</constant> for <parameter>buffer</parameter>. Furthermore, <parameter>offset</parameter> must be
an integer multiple of the value of <constant>GL_TEXTURE_BUFFER_OFFSET_ALIGNMENT</constant>.
<parameter>internalformat</parameter> specifies the storage format, and must be one of the following sized internal formats:
