wchar_t *wcscpy(wchar_t *__restrict <[s1]>,
const wchar_t *__restrict <[s2]>);
DESCRIPTION
The <<wcscpy>> function copies the wide-character string pointed to by
<[s2]> (including the terminating null wide-character code) into the
array pointed to by <[s1]>. If copying takes place between objects that
overlap, the behaviour is undefined.
RETURNS
The <<wcscpy>> function returns <[s1]>; no return value is reserved to
indicate an error.
PORTABILITY
<<wcscpy>> is ISO/IEC 9899/AMD1:1995 (ISO C).
