Locate the first occurrence of a wide character in a buffer
#include <wchar.h>
wchar_t * wmemchr( const wchar_t * ws,
wchar_t wc,
size_t n );
- ws
- The buffer that you want to search.
- wc
- The character that you're looking for.
- n
- The number of wide characters to search in the buffer.

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.
