border="0"> The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the
|
|
requirements described here and the ISO C standard is unintentional. This volume of IEEE Std 1003.1-2001 defers to

the ISO C standard. <img src="../images/opt-end.gif" alt="[Option End]" border="0"></div>
|
|
|
|
<p>The <i>wcsncat</i>() function shall append not more than <i>n</i> wide-character codes (a null wide-character code and
|
|
wide-character codes that follow it are not appended) from the array pointed to by <i>ws2</i> to the end of the wide-character
|
|
string pointed to by <i>ws1</i>. The initial wide-character code of <i>ws2</i> shall overwrite the null wide-character code at the
|
|
end of <i>ws1</i>. A terminating null wide-character code shall always be appended to the result. If copying takes place between
|
|
objects that overlap, the behavior is undefined.</p>
