In particular,<i>putc</i>(<i>c</i>, *<i>f</i>++)will not necessarily work correctly.Therefore, use of this interface is not recommended in such situations;<i><a href="fputc.html">fputc()</a></i>should be used instead.</blockquote><h4><a name = "tag_000_007_1751">&nbsp;</a>FUTURE DIRECTIONS</h4><blockquote>None.</blockquote><h4><a name = "tag_000_007_1752">&nbsp;</a>SEE ALSO</h4><blockquote><i><a href="fputc.html">fputc()</a></i>,<i><a href="stdio.h.html">&lt;stdio.h&gt;</a></i>.</blockquote><h4>DERIVATION</h4><blockquote>Derived from Issue 1 of the SVID.</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>
