NAME
wmemcpy - copy wide characters in memory
SYNOPSIS
#include <wchar.h>
wchar_t *wmemcpy(wchar_t *restrict ws1, const wchar_t
*restrict ws2,
size_t n);
DESCRIPTION
The wmemcpy() function shall copy n wide characters from
the object pointed to by ws2 to the object pointed
to by ws1. 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 ws1 and
ws2 are valid pointers, and the function shall copy
zero wide characters.
RETURN VALUE
The wmemcpy() function shall return the value of ws1.
