| <h3 class="section">6.8 <code>wcscmp</code>—compare two wide-character strings</h3> |
| |
| <p><strong>Synopsis</strong> |
| <pre class="example"> #include <wchar.h> |
| int wcscmp(const wchar_t *<var>s1</var>, *<var>s2</var>); |
| |
| </pre> |
| <p><strong>Description</strong><br> |
| The <code>wcscmp</code> function compares the wide-character string pointed to |
| by <var>s1</var> to the wide-character string pointed to by <var>s2</var>. |
| |
| <p>The sign of a non-zero return value is determined by the sign of the |
| difference between the values of the first pair of wide-character codes |
| that differ in the objects being compared. |
| |
| <p><br> |
| <strong>Returns</strong><br> |
| Upon completion, <code>wcscmp</code> returns an integer greater than, equal to |
| or less than 0, if the wide-character string pointed to by <var>s1</var> is |
| greater than, equal to or less than the wide-character string pointed |
| to by <var>s2</var> respectively. |
| |
| <p><br> |
| <strong>Portability</strong><br> |
| <code>wcscmp</code> is ISO/IEC 9899/AMD1:1995 (ISO C). |
| |
| <p>No supporting OS subroutines are required. |
