NAME
wcscat, wcsncat
— concatenate wide
strings
SYNOPSIS
#include
<wchar.h>
wchar_t *
wcscat(wchar_t
* restrict s, const
wchar_t * restrict append);
wchar_t *
wcsncat(wchar_t * restrict s,
const wchar_t * restrict append,
size_t count);
DESCRIPTION
The
wcscat()
and wcsncat() functions append a copy of the wide
string append to the end of the wide string
s, then add a terminating null wide character (L'\0').
The wide string s must have sufficient space to hold
the result.
The
wcsncat()
function appends not more than count wide characters
where space for the terminating null wide character should not be included
in count.
RETURN VALUES
The wcscat() and
wcsncat() functions return the pointer
s.

STANDARDS
The wcscat() and
wcsncat() functions conform to
ISO/IEC 9899:1999 (“ISO C99”)
and were first introduced in ISO/IEC 9899/AMD1:1995
(“ISO C90, Amendment 1”).
HISTORY
The wcscat() and
wcsncat() functions were ported from
NetBSD and first appeared in
OpenBSD 3.8.
CAVEATS
Using the functions wcscat() and
wcsncat() is very error-prone with respect to buffer
overflows; see the EXAMPLES section in
strcat(3) for correct usage. Using
wcslcat(3) is a better choice in most cases.
