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
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.

44 No return values are reserved to indicate an error.
