| <h3 class="section">6.2 <code>wmemcmp</code>—compare wide characters in memory</h3> |
| |
| <p><strong>Synopsis</strong> |
| <pre class="example"> #include <wchar.h> |
| int wmemcmp(const wchar_t *<var>s1</var>, const wchar_t *<var>s2</var>, size_t <var>n</var>); |
| |
| </pre> |
| <p><strong>Description</strong><br> |
| The <code>wmemcmp</code> function compares the first <var>n</var> wide characters of the |
| object pointed to by <var>s1</var> to the first <var>n</var> wide characters of the |
| object pointed to by <var>s2</var>. This function is not affected by locale |
| and all wchar_t values are treated identically. The null wide character |
| and wchar_t values not corresponding to valid characters are not treated |
| specially. |
| |
| <p>If <var>n</var> is zero, <var>s1</var> and <var>s2</var> must be a valid pointers and the |
| function behaves as if the two objects compare equal. |
| |
| <p><br> |
| <strong>Returns</strong><br> |
| The <code>wmemcmp</code> function returns an integer greater than, equal to, |
| or less than zero, accordingly as the object pointed to by <var>s1</var> is |
| greater than, equal to, or less than the object pointed to by <var>s2</var>. |
| |
| <p><br> |
| <strong>Portability</strong><br> |
| <code>wmemcmp</code> is ISO/IEC 9899/AMD1:1995 (ISO C). |
| |
| <p>No supporting OS subroutines are required. |
