WCSCPY(3P) POSIX Programmer's Manual WCSCPY(3P)
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior), or
the interface may not be implemented on Linux.
wcpcpy, wcscpy — copy a wide-character string, returning a pointer to
its end
#include <wchar.h>
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(): 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.1‐2008 defers to the ISO C standard.
The 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.
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.
The following sections are informative.
