<h3 class="section">6.26 <code>wcstok</code>—get next token from a string</h3>
<a name="index-wcstok"></a>
<p><strong>Synopsis</strong>
</p><div class="example">
<pre class="example">#include <wchar.h>
wchar_t *wcstok(wchar_t *__restrict <var>source</var>,
const wchar_t *__restrict <var>delimiters</var>,
wchar_t **__restrict <var>lasts</var>);
</pre></div>
<p><strong>Description</strong><br>
The <code>wcstok</code> function is the wide-character equivalent of the
<code>strtok_r</code> function (which in turn is the same as the <code>strtok</code>
function with an added argument to make it thread-safe).
</p>
<p>The <code>wcstok</code> function is used to isolate (one at a time)
sequential tokens in a null-terminated wide-character string,
<code>*<var>source</var></code>. A token is defined as a substring not containing
any wide-characters from <code>*<var>delimiters</var></code>.
</p>
<p>The first time that <code>wcstok</code> is called, <code>*<var>source</var></code> should
be specified with the wide-character string to be searched, and
<code>*<var>lasts</var></code>–but not <code>lasts</code>, which must be non-NULL–may be
random; subsequent calls, wishing to obtain further tokens from
the same string, should pass a null pointer for <code>*<var>source</var></code>
instead but must supply <code>*<var>lasts</var></code> unchanged from the last
call. The separator wide-character string, <code>*<var>delimiters</var></code>,
must be supplied each time and may change between calls.
A pointer to placeholder <code>*<var>lasts</var></code> must be supplied by
the caller, and is set each time as needed to save the state
by <code>wcstok</code>. Every call to <code>wcstok</code> with <code>*<var>source</var></code>
== <code>NULL</code> must pass the value of <code>*<var>lasts</var></code> as last set
by <code>wcstok</code>.
</p>
<p>The <code>wcstok</code> function returns a pointer to the beginning of each
subsequent token in the string, after replacing the separator
wide-character itself with a null wide-character. When no more tokens
remain, a null pointer is returned.
</p>
<br>
<p><strong>Returns</strong><br>
<code>wcstok</code> returns a pointer to the first wide character of a token, or
<code>NULL</code> if there is no token.
</p>
<br>
<p><strong>Portability</strong><br>
<code>wcstok</code> is C99 and POSIX.1-2001.
</p>
<p><code>wcstok</code> requires no supporting OS subroutines.
