memory buffer for holding <tt class="literal">NUL</tt>-terminated strings. The
<i class="structfield"><tt>data</tt></i> field points to the beginnning of the
string, the length of which is given by the
<i class="structfield"><tt>used</tt></i> field. The current size of memory
allocated is given by the <i class="structfield"><tt>length</tt></i> field. It
is not recommended that the fields of a buffer are manipulated
directly. The <i class="structfield"><tt>data</tt></i> pointer may change when
the buffer is modified.</p><p>A buffer is created using <a href="refbufcr.html#ne_buffer_create">ne_buffer_create</a> or <a href="refbufcr.html#ne_buffer_create_sized">ne_buffer_ncreate</a>, and destroyed using <a href="refbufdest.html#ne_buffer_destroy">ne_buffer_destroy</a> or <a href="refbufdest.html#ne_buffer_finish">ne_buffer_finish</a>.
The functions <a href="refbufapp.html#ne_buffer_append">ne_buffer_append</a>, <a href="refbufapp.html#ne_buffer_zappend">ne_buffer_zappend</a> and <a href="refbufapp.html#ne_buffer_concat">ne_buffer_concat</a> are
used to append data to a buffer.</p><p>If the string referenced by the
<i class="structfield"><tt>data</tt></i> pointer is modified directly (rather
than using one of the functions listed above),
<tt class="function">ne_buffer_altered</tt> must be called.</p></div></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="refresolve.html">Prev</a></td><td width="20%" align="center"><a accesskey="u" href="ref.html">Up</a></td><td width="40%" align="right"><a accesskey="n" href="refbufapp.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">ne_addr_resolve</td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top">ne_buffer_append</td></tr></table></div></body></html>
