|
|
|
|
<blockquote>
|
|
<p>Since it may be implemented as a macro, <i>putwc</i>() may treat a <i>stream</i> argument with side effects incorrectly. In
|
|
particular, <i>putwc</i>(<i>wc</i>,*<i>f</i>++) need not work correctly. Therefore, use of this function is not recommended; <a
|
|
href="../functions/fputwc.html"><i>fputwc</i>()</a> should be used instead.</p>
