If copying takes place between 49objects that overlap, the behaviour is undefined. 50 51 <p><br> 52<strong>Returns</strong><br> 53The <code>wcscat</code> function returns <var>s1</var>; 54no return value is reserved to indicate an error. 55 56 <p><br> 57<strong>Portability</strong><br> 58<code>wcscat</code> is ISO/IEC 9899/AMD1:1995 (ISO C). 59 60 <p>No supporting OS subroutines are required. 61 62 <p><br> 63 64 </body></html> 65 66
