21 The functionality described on this reference page is aligned with the
22 ISO C standard. Any conflict between the requirements described here
23 and the ISO C standard is unintentional. This volume of POSIX.1‐2017
24 defers to the ISO C standard.
25
26 The wcsncat() function shall append not more than n wide-character
27 codes (a null wide-character code and wide-character codes that follow
28 it are not appended) from the array pointed to by ws2 to the end of the
29 wide-character string pointed to by ws1. The initial wide-character
30 code of ws2 shall overwrite the null wide-character code at the end of
31 ws1. A terminating null wide-character code shall always be appended
32 to the result. If copying takes place between objects that overlap, the
33 behavior is undefined.
34
36 The wcsncat() function shall return ws1; no return value is reserved to
37 indicate an error.
