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.1-2017 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.
