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 (“POSIX.1”) 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.
EXAMPLES
None.
APPLICATION USAGE
None.
RATIONALE
None.
FUTURE DIRECTIONS
None.

The wcsncat () prototype is updated for
alignment with the ISO/IEC 9899:1999
(“ISO C99”) standard.
