PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (con-
       sult 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.
