        <para>
            <function>glBindBuffersBase</function> binds a set of <parameter>count</parameter> buffer objects whose names
            are given in the array <parameter>buffers</parameter> to the <parameter>count</parameter> consecutive binding
            points starting from index <parameter>first</parameter> of the array of targets specified
            by <parameter>target</parameter>. If <parameter>buffers</parameter> is <constant>NULL</constant> then
            <function>glBindBuffersBase</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>glBindBufferBase</refentrytitle></citerefentry>,
            with the exception that the non-indexed <parameter>target</parameter> is not changed by <function>glBindBuffersBase</function>:
        </para>
<programlisting>    for (i = 0; i &lt; count; i++) {
        if (buffers != NULL) {
            glBindBufferBase(target, first + i, buffers[i]);
        } else {
            glBindBufferBase(target, first + i, 0);
        }
    }</programlisting>
        <para>
            Each entry in <parameter>buffers</parameter> will be checked individually and if found to be invalid, the state
            for that buffer binding index will not be changed and an error will be generated. However, the state for
            other buffer binding indices referenced by the command will still be updated.
