WCSNCPY(3P)                POSIX Programmer's Manual               WCSNCPY(3P)

PROLOG
       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.
NAME
       wcsncpy - copy part of a wide-character string
SYNOPSIS
       #include <wchar.h>
       wchar_t *wcsncpy(wchar_t *restrict ws1, const wchar_t *restrict ws2,
              size_t n);

DESCRIPTION
       The wcsncpy() function shall copy not more than n wide-character  codes
       (wide-character  codes  that  follow a null wide-character code are not
       copied) from the array pointed to by ws2 to the  array  pointed  to  by
       ws1.  If copying takes place between objects that overlap, the behavior
       is undefined.
       If the array pointed to by ws2  is  a  wide-character  string  that  is
       shorter than n wide-character codes, null wide-character codes shall be
       appended to the copy in the array pointed to by ws1, until n wide-char-
       acter codes in all are written.
RETURN VALUE
       The wcsncpy() function shall return ws1; no return value is reserved to
       indicate an error.
ERRORS
       No errors are defined.
       The following sections are informative.
EXAMPLES
       None.
APPLICATION USAGE
       If there is no null wide-character code in the first  n  wide-character
       codes  of  the  array  pointed to by ws2, the result is not null-termi-
       nated.
RATIONALE
       None.
FUTURE DIRECTIONS
       None.
