wmemchr - find a wide character in memory
wchar_t *wmemchr(const wchar_t *ws, wchar_t wc, size_t n);
The wmemchr() function shall locate the first occurrence of wc in the initial n wide char-
acters of the object pointed to by ws. This function shall not be affected by locale and
all wchar_t values shall be treated identically. The null wide character and wchar_t val-
ues not corresponding to valid characters shall not be treated specially.
If n is zero, the application shall ensure that ws is a valid pointer and the function
behaves as if no valid occurrence of wc is found.
The wmemchr() function shall return a pointer to the located wide character, or a null
pointer if the wide character does not occur in the object.
No errors are defined.
