### 6.5 `wmemset`—set wide characters in memory

Synopsis

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

Description
The `wmemset` function copies the value of c into each of the first n wide characters of the object pointed to by 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 copies zero wide characters.

Returns
The `wmemset` function returns the value of s.

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

No supporting OS subroutines are required.
