NAME

12       wcsstr - find a wide-character substring
13

SYNOPSIS

15       #include <wchar.h>
16
17       wchar_t *wcsstr(const wchar_t *restrict ws1,
18              const wchar_t *restrict ws2);

DESCRIPTION

22       The wcsstr() function shall locate the first occurrence  in  the  wide-
23       character  string  pointed to by ws1 of the sequence of wide characters
24       (excluding the terminating null wide character) in  the  wide-character
25       string pointed to by ws2.
26

RETURN VALUE

28       Upon  successful  completion,  wcsstr()  shall  return a pointer to the
29       located wide-character string, or a null pointer if the  wide-character
30       string is not found.
31
32       If ws2 points to a wide-character string with zero length, the function
33       shall return ws1.
