| |
| <p><strong>Synopsis</strong> |
| <pre class="example"> #include <wchar.h> |
| wchar_t *wcsstr(const wchar_t *<var>big</var>, const wchar_t *<var>little</var>); |
| |
| </pre> |
| <p><strong>Description</strong><br> |
| The <code>wcsstr</code> function locates the first occurrence in the |
| wide-character string pointed to by <var>big</var> of the sequence of |
| wide characters (excluding the terminating null wide character) in the |
| wide-character string pointed to by <var>little</var>. |
| |
| <p><br> |
| <strong>Returns</strong><br> |
| On successful completion, <code>wcsstr</code> returns a pointer to the located |
| wide-character string, or a null pointer if the wide-character string |
| is not found. |
| |
| <p>If <var>little</var> points to a wide-character string with zero length, |
| the function returns <var>big</var>. |
| |
| <p><br> |
| <strong>Portability</strong><br> |
| <code>wcsstr</code> is ISO/IEC 9899/AMD1:1995 (ISO C). |
