ANSI_SYNOPSIS

|
|
#include <wchar.h>
|

|
|
wchar_t *wcsncat(wchar_t *<[s1]>, const wchar_t *<[s2]>, size_t <[n]>);

TRAD_SYNOPSIS
|
| 10 |
|
|
wchar_t *wcsncat(<[s1]>, <[s2]>, <[n]>
|
| 11 |
|
|
wchar_t *<[s1]>;
|
| 12 |
|
|
const wchar_t *<[s2]>;

DESCRIPTION
|
| 16 |
|
|
The <<wcsncat>> function appends not more than <[n]> wide-character
|
| 17 |
|
|
codes (a null wide-character code and wide-character codes that follow
|
| 18 |
|
|
it are not appended) from the array pointed to by <[s2]> to the end of
|
| 19 |
|
|
the wide-character string pointed to by <[s1]>. The initial
|
| 20 |
|
|
wide-character code of <[s2]> overwrites the null wide-character code
|
| 21 |
|
|
at the end of <[s1]>.
|
| 22 |
|
|
A terminating null wide-character code is always appended to the result.
|
| 23 |
|
|
If copying takes place between objects that overlap, the behaviour is
|
| 24 |
|
|
undefined.
|
| 25 |
|
|
|
| 26 |
|
|
RETURNS
|
| 27 |
|
|
The <<wcsncat>> function returns <[s1]>; no return value is reserved to
|
| 28 |
|
|
indicate an error.
|
| 29 |
|
|
|
| 30 |
|
|
PORTABILITY
|
| 31 |
|
|
<<wcsncat>> is ISO/IEC 9899/AMD1:1995 (ISO C).
|
| 32 |
|
|
|
| 33 |
|
|
No supporting OS subroutines are required.
