<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:
|
||
|
|
"tolower" and "toupper".
|
||
|
|
</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.
|
||
|
