Use the -l c option to qcc to link against this library. This library is usually included automatically.
The wmemchr() function locates the first occurrence of wc in the first n wide characters of the buffer pointed to by ws.
The wmemchr() function is locale-independent and treats all wchar_t values identically, even if they're null or invalid characters.
A pointer to the located character, or NULL if wc couldn't be found.
