<code class="function">ne_buffer_zappend</code> functions append a string to
the end of a buffer; extending the buffer as necessary.  The
<code class="parameter">len</code> passed to
<code class="function">ne_buffer_append</code> specifies the length of the
string to append; there must be no <code class="literal">NUL</code> terminator in the first
<code class="parameter">len</code> bytes of the string.
<code class="function">ne_buffer_zappend</code> must be passed a
<code class="literal">NUL</code>-terminated string.</p><p>The <code class="function">ne_buffer_concat</code> function takes
a variable-length argument list following <code class="parameter">str</code>;
each argument must be a <em class="type">char *</em> pointer to a
<code class="literal">NUL</code>-terminated string.  A <code class="literal">NULL</code> pointer must be given as the last
argument to mark the end of the list.  The strings (including
<code class="parameter">str</code>) are appended to the buffer in the order
given. None of the strings passed to
<code class="function">ne_buffer_concat</code> are modified.</p></div><div class="refsect1"><a name="idm140368851052608"></a><h2>Examples</h2><p>The following code will output "<code class="literal">Hello, world.
