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

[CX] 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 IEEE Std 1003.1-2001 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.
