### 8.1 `wmemchr`—find a wide character in memory ¶

Synopsis

    #include <wchar.h>
    wchar_t	*wmemchr(const wchar_t *s, wchar_t c, size_t n);

Description
The `wmemchr` function locates the first occurrence of c in the initial n wide characters of the object pointed to be s. This function is not affected by locale and all wchar_t values are treated identically. The null wide character and wchar_t values not corresponding to valid characters are not treated specially.

If n is zero, s must be a valid pointer and the function behaves as if no valid occurrence of c is found.

Returns
The `wmemchr` function returns a pointer to the located wide character, or a null pointer if the wide character does not occur in the object.

Portability
`wmemchr` is ISO/IEC 9899/AMD1:1995 (ISO C).

No supporting OS subroutines are required.
