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.1-2017 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.
The following sections are informative.
EXAMPLES
None.
APPLICATION USAGE
