FUNCTION
<<wmemset>>---set wide characters in memory
ANSI_SYNOPSIS
#include <wchar.h>
wchar_t *wmemset(wchar_t *<[s]>, wchar_t <[c]>, size_t <[n]>);
TRAD_SYNOPSIS
wchar_t *wmemset(<[s]>, <[c]>, <[n]>
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).
