<p><strong>Synopsis</strong>
</p><div class="example">
<pre class="example">#include &lt;wctype.h&gt;
wctrans_t wctrans(const char *<var>c</var>);

#include &lt;wctype.h&gt;
wctrans_t wctrans_l(const char *<var>c</var>, locale_t <var>locale</var>);

</pre></div>
<p><strong>Description</strong><br>
<code>wctrans</code> is a function which takes a string <var>c</var> and gives back
the appropriate wctrans_t type value associated with the string,
if one exists.  The following values are guaranteed to be recognized:
&quot;tolower&quot; and &quot;toupper&quot;.
</p>
<p><code>wctrans_l</code> is like <code>wctrans</code> but performs the function based on the
locale specified by the locale object locale.  If <var>locale</var> is
LC_GLOBAL_LOCALE or not a valid locale object, the behaviour is undefined.
</p>
<br>
<p><strong>Returns</strong><br>
<code>wctrans</code>, <code>wctrans_l</code> return 0 and sets <code>errno</code> to <code>EINVAL</code> if the
given name is invalid.  Otherwise, it returns a valid non-zero wctrans_t
value.
</p>
<br>
<p><strong>Portability</strong><br>
<code>wctrans</code> is C99.
<code>wctrans_l</code> is POSIX-1.2008.
</p>
<p>No supporting OS subroutines are required.
