NAME
wmemset — set wide
characters in memory
SYNOPSIS
#include
<wchar.h>
wchar_t *wmemset(wchar_t *ws, wchar_t wc, size_t n);
DESCRIPTION
[CX] The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of POSIX.1-2008 defers to the ISO C standard.
The wmemset () function shall copy
the value of wc into
each of the first n wide characters of the object pointed
to by ws. This function shall not be affected by locale
and all wchar_t values shall be treated identically. The
null wide character and wchar_t values not corresponding
to valid characters shall not be treated specially.
If n is zero, the application shall ensure that ws is a valid pointer, and the function shall copy zero wide characters.
RETURN VALUE
The wmemset () functions shall return the
value of ws.
