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

       wcsncat — concatenate a wide-character string with part of another

SYNOPSIS

       #include <wchar.h>

       wchar_t *wcsncat(wchar_t *restrict ws1, const wchar_t *restrict ws2,
           size_t n);

DESCRIPTION

       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  wcsncat()  function  shall  append not more than n wide-character codes (a null wide-
       character code and wide-character codes that follow it are not appended)  from  the  array
       pointed  to by ws2 to the end of the wide-character string pointed to by ws1.  The initial
       wide-character code of ws2 shall overwrite the null wide-character code at the end of ws1.
       A  terminating null wide-character code shall always be appended to the result. If copying
       takes place between objects that overlap, the behavior is undefined.

RETURN VALUE

       The wcsncat() function shall return ws1; no return value is reserved to indicate an error.

ERRORS

       No errors are defined.
