SYNOPSIS

       #include <wchar.h>

       wchar_t *wcsstr(const wchar_t *restrict ws1,

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
