       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.

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

       #include <wchar.h>

       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 _w_c_s_n_c_a_t() 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 _w_s_2 to the end of the
       wide-character string pointed to by _w_s_1.  The initial wide-character
       code of _w_s_2 shall overwrite the null wide-character code at the end of
       _w_s_1.  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.

RREETTUURRNN VVAALLUUEE
       The _w_c_s_n_c_a_t() function shall return _w_s_1; no return value is reserved to
       indicate an error.

       No errors are defined.
