| <pre class="example"> #include <wchar.h> |
| wchar_t *wcsdup(const wchar_t *<var>str</var>); |

| <p><strong>Description</strong><br> |
| <code>wcsdup</code> allocates a new wide character string using <code>malloc</code>, |
| and copies the content of the argument <var>str</var> into the newly |
| allocated string, thus making a copy of <var>str</var>. |
| |
| <p><br> |
| <strong>Returns</strong><br> |
| <code>wcsdup</code> returns a pointer to the copy of <var>str</var> if enough |
| memory for the copy was available. Otherwise it returns NULL |
| and errno is set to ENOMEM. |
