            <function>glBindBuffersRange</function> binds a set of <parameter>count</parameter> ranges from buffer objects whose names
            are given in the array <parameter>buffers</parameter> to the <parameter>count</parameter> consecutive binding
            points starting from index <parameter>index</parameter> of the array of targets specified
            by <parameter>target</parameter>. <parameter>offsets</parameter> specifies the address of an array containing
            <parameter>count</parameter> starting offsets within the buffers, and <parameter>sizes</parameter> specifies the
            adderess of an array of <parameter>count</parameter> sizes of the ranges. If <parameter>buffers</parameter> is <constant>NULL</constant> then
            <parameter>offsets</parameter> and <parameter>sizes</parameter> are ignored and <function>glBindBuffersRange</function> unbinds any
            buffers that are currently bound to the referenced binding points. Assuming no errors are generated, it is equivalent to the following
            pseudo-code, which calls <citerefentry><refentrytitle>glBindBufferRange</refentrytitle></citerefentry>:
