NAME
       wcswcs - find a wide substring (LEGACY)
SYNOPSIS
       #include <wchar.h>
       wchar_t *wcswcs(const wchar_t *ws1, const wchar_t *ws2);

DESCRIPTION
       The wcswcs() function shall locate the first occurrence  in  the  wide-
       character  string  pointed  to by ws1 of the sequence of wide-character
       codes (excluding the terminating null wide-character code) in the wide-
       character string pointed to by ws2.
RETURN VALUE
       Upon  successful  completion,  wcswcs()  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.
