This 44function is not affected by locale and all wchar_t values are treated 45identically. The null wide character and wchar_t values not 46corresponding to valid characters are not treated specially. 47 48 <p>If <var>n</var> is zero, <var>s</var> must be a valid pointer and the function 49behaves as if no valid occurrence of <var>c</var> is found. 50 51 <p><br> 52<strong>Returns</strong><br> 53The <code>wmemchr</code> function returns a pointer to the located 54wide character, or a null pointer if the wide character does not occur 55in the object. 56 57 <p><br> 58<strong>Portability</strong><br> 59<code>wmemchr</code> is ISO/IEC 9899/AMD1:1995 (ISO C). 60 61 <p>No supporting OS subroutines are required. 62 63 <p><br> 64 65 </body></html> 66 67
