15 The wmemchr() function shall locate the first occurrence of wc in the
16 initial n wide characters of the object pointed to by ws. This function
17 shall not be affected by locale and all wchar_t values shall be treated
18 identically. The null wide character and wchar_t values not correspond‐
19 ing to valid characters shall not be treated specially.
20
21 If n is zero, the application shall ensure that ws is a valid pointer
22 and the function behaves as if no valid occurrence of wc is found.
23
25 The wmemchr() function shall return a pointer to the located wide char‐
26 acter, or a null pointer if the wide character does not occur in the
27 object.
