NAME
       wcsstr - find a wide-character substring


SYNOPSIS
       #include <wchar.h>

       wchar_t *wcsstr(const wchar_t *restrict ws1,
              const wchar_t *restrict ws2);


DESCRIPTION
       The wcsstr() function shall locate the first occurrence in the wide-character string pointed to by ws1 of
       the sequence of wide characters (excluding the terminating null wide  character)  in  the  wide-character
       string pointed to by ws2.


RETURN VALUE
       Upon  successful  completion,  wcsstr() shall return a pointer to the located wide-character string, or a
       null pointer if the wide-character string is not found.

       If ws2 points to a wide-character string with zero length, the function shall return ws1.
