| <h3 class="section">6.6 <code>wcscat</code>—concatenate two wide-character strings</h3> |
| |
| <p><a name="index-wcscat-415"></a><strong>Synopsis</strong> |
| <pre class="example"> #include <wchar.h> |
| wchar_t *wcscat(wchar_t *<var>s1</var>, const wchar_t *<var>s2</var>); |
| |
| </pre> |
| <p><strong>Description</strong><br> |
| The <code>wcscat</code> function appends a copy of the wide-character string |
| pointed to by <var>s2</var> (including the terminating null wide-character |
| code) to the end of the wide-character string pointed to by <var>s1</var>. |
| The initial wide-character code of <var>s2</var> overwrites the null |
| wide-character code at the end of <var>s1</var>. If copying takes place between |
| objects that overlap, the behaviour is undefined. |
| |
| <p><br> |
| <strong>Returns</strong><br> |
| The <code>wcscat</code> function returns <var>s1</var>; |
| no return value is reserved to indicate an error. |
| |
| <p><br> |
| <strong>Portability</strong><br> |
| <code>wcscat</code> is ISO/IEC 9899/AMD1:1995 (ISO C). |
| |
| <p>No supporting OS subroutines are required. |
