| <h3 class="section">6.23 <code>wcsrchr</code>—wide-character string scanning operation</h3> |
| |
| <p><strong>Synopsis</strong> |
| <pre class="example"> #include <wchar.h> |
| wchar_t *wcsrchr(const wchar_t *<var>s</var>, wchar_t <var>c</var>); |
| |
| </pre> |
| <p><strong>Description</strong><br> |
| The <code>wcsrchr</code> function locates the last occurrence of <var>c</var> in the |
| wide-character string pointed to by <var>s</var>. The value of <var>c</var> must be a |
| character representable as a type wchar_t and must be a wide-character |
| code corresponding to a valid character in the current locale. |
| The terminating null wide-character code is considered to be part of |
| the wide-character string. |
| |
| <p><br> |
| <strong>Returns</strong><br> |
| Upon successful completion, <code>wcsrchr</code> returns a pointer to the |
| wide-character code or a null pointer if <var>c</var> does not occur in the |
| wide-character string. |
| |
| <p><br> |
| <strong>Portability</strong><br> |
| <code>wcsrchr</code> is ISO/IEC 9899/AMD1:1995 (ISO C). |
| |
| <p>No supporting OS subroutines are required. |
