       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.
