+
+	<para>The <function>ne_buffer_clear</function> function sets
+the string stored in <parameter>buf</parameter> to be the empty string
+(<literal>""</literal>).</para>
+
+	<para>The <function>ne_buffer_altered</function> function must
+be used after the string stored in the buffer
+<parameter>buf</parameter> is modified by directly rather than using
+<xref linkend="ne_buffer_append"/>, <xref linkend="ne_buffer_zappend"/> 
+or <xref linkend="ne_buffer_concat"/>.</para>
+
+	<para>The <function>ne_buffer_grow</function> function
+ensures that at least <parameter>size</parameter> bytes are allocated
+for the string; this can be used if a large amount of data is going to
+be appended to the buffer and may result in more efficient memory
+allocation.</para>
