A zero valued<b>mbstate_t</b>object is at least one way to describe an initial conversion state.  Azero valued<b>mbstate_t</b>object can be used to initiate conversion involving any charactersequence, in any LC_CTYPE category setting.  </blockquote><h4><a name = "tag_000_007_545">&nbsp;</a>FUTURE DIRECTIONS</h4><blockquote>None.</blockquote><h4><a name = "tag_000_007_546">&nbsp;</a>SEE ALSO</h4><blockquote><i><a href="mbrlen.html">mbrlen()</a></i>,<i><a href="mbrtowc.html">mbrtowc()</a></i>,<i><a href="wcrtomb.html">wcrtomb()</a></i>,<i><a href="mbsrtowcs.html">mbsrtowcs()</a></i>,<i><a href="wcsrtombs.html">wcsrtombs()</a></i>,<i><a href="wchar.h.html">&lt;wchar.h&gt;</a></i>.</blockquote><h4>DERIVATION</h4><blockquote>Derived from the ISO/IEC 9899:1990/Amendment 1:1995 (E).</blockquote><hr size=2 noshade><center><font size=2>UNIX &reg; is a registered Trademark of The Open Group.<br>Copyright &copy; 1997 The Open Group<br> [ <a href="../index.html">Main Index</a> | <a href="../xshix.html">XSH</a> | <a href="../xcuix.html">XCU</a> | <a href="../xbdix.html">XBD</a> | <a href="../cursesix.html">XCURSES</a> | <a href="../xnsix.html">XNS</a> ]</font></center><hr size=2 noshade></body></html>
