23 For wcscpy(): The functionality described on this reference page is
24 aligned with the ISO C standard. Any conflict between the requirements
25 described here and the ISO C standard is unintentional. This volume of
26 POSIX.1‐2008 defers to the ISO C standard.
27
28 The wcpcpy() and wcscpy() functions shall copy the wide-character
29 string pointed to by ws2 (including the terminating null wide-character
30 code) into the array pointed to by ws1.
31
32 The application shall ensure that there is room for at least
33 wcslen(ws2)+1 wide characters in the ws1 array, and that the ws2 and
34 ws1 arrays do not overlap.
35
36 If copying takes place between objects that overlap, the behavior is
37 undefined.
38
40 The wcpcpy() function shall return a pointer to the terminating null
41 wide-character code copied into the ws1 buffer.
42
43 The wcscpy() function shall return ws1.

45 No return values are reserved to indicate an error.
