WCSCPY(3)                  POSIX Programmer's Manual                 WCSCPY(3)



PROLOG
       This manual page is part of the POSIX Programmer's Manual.  The OS
       implementation of this interface may differ (consult the corresponding
       OS manual page for details of OS behavior), or the interface may not be
       implemented on OS.

NAME
       wcpcpy, wcscpy -- copy a wide-character string, returning a pointer to
       its end

SYNOPSIS
       #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);

DESCRIPTION
       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.1-2017 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.

RETURN VALUE
       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.
