NAME
wcpcpy wcscpy
— copy a wide-character string, returning a pointer
to its end
SYNOPSIS
#include
<wchar.h>
[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);
DESCRIPTION
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.
RETURN VALUE
[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.
ERRORS
No errors are defined.
