PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
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.
