|
|
|
<blockquote>
|
|
<p>The <a href="../functions/strchr.html"><i>strchr</i>()</a> function is preferred over this function.</p>
|
|
|
|
<p>For maximum portability, it is recommended to replace the function call to <i>index</i>() as follows:</p>
|
|
|
|
<pre>
|
|
<tt>#define index(a,b) strchr((a),(b))
|
|
</tt>
