PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
7       implementation of this interface may differ (consult the  corresponding
8       Linux  manual page for details of Linux behavior), or the interface may
9       not be implemented on Linux.

NAME

12       wcpcpy, wcscpy — copy a wide-character string, returning a  pointer  to
13       its end
14

SYNOPSIS

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

DESCRIPTION

22       For  wcscpy():  The  functionality  described on this reference page is
23       aligned with the ISO C standard. Any conflict between the  requirements
24       described  here and the ISO C standard is unintentional. This volume of
25       POSIX.1‐2017 defers to the ISO C standard.
26
27       The wcpcpy() and  wcscpy()  functions  shall  copy  the  wide-character
28       string pointed to by ws2 (including the terminating null wide-character
29       code) into the array pointed to by ws1.
30
31       The  application  shall  ensure  that  there  is  room  for  at   least
32       wcslen(ws2)+1  wide  characters  in the ws1 array, and that the ws2 and
33       ws1 arrays do not overlap.
34
35       If copying takes place between objects that overlap,  the  behavior  is
36       undefined.
37

RETURN VALUE

39       The  wcpcpy()  function  shall return a pointer to the terminating null
40       wide-character code copied into the ws1 buffer.
41
42       The wcscpy() function shall return ws1.
43
44       No return values are reserved to indicate an error.
