A terminating 48null wide character is always added unless <var>siz</var> is 0. Thus, 49the maximum number of wide characters that can be appended from 50<var>src</var> is <var>siz</var> - 1. If copying takes place between objects 51that overlap, the behaviour is undefined. 52 53 <p><br> 54<strong>Returns</strong><br> 55Wide-character string length of initial <var>dst</var> plus the 56wide-character string length of <var>src</var> (does not include 57terminating null wide-characters). If the return value is 58greater than or equal to <var>siz</var>, then truncation occurred and 59not all wide characters from <var>src</var> were appended. 60 61 <p><br> 62<strong>Portability</strong><br> 63No supporting OS subroutines are required. 64 65 <p><br> 66 67 </body></html> 68 69
