wcpcpy, wcscpy - copy a wide-character string, returning a pointer to its end
[CX] wchar_t *wcpcpy(wchar_t *restrict ws1, const wchar_t *restrict ws2);
wchar_t *wcscpy(wchar_t *restrict ws1, const wchar_t *restrict ws2);
For wcscpy(): [CX] The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of POSIX.1-2017 defers to the ISO C standard.
The [CX] wcpcpy() and wcscpy() functions shall copy the wide-character string pointed to by ws2 (including the terminating null wide-character code) into the array pointed to by ws1.
The application shall ensure that there is room for at least wcslen(ws2)+1 wide characters in the ws1 array, and that the ws2 and ws1 arrays do not overlap.
If copying takes place between objects that overlap, the behavior is undefined.
[CX] The wcpcpy() function shall return a pointer to the terminating null wide-character code copied into the ws1 buffer.
The wcscpy() function shall return ws1.
No return values are reserved to indicate an error.
No errors are defined.
