| FUNCTION |
| <<wcsncat>>---concatenate part of two wide-character strings |
| |
| ANSI_SYNOPSIS |
| #include <wchar.h> |
| wchar_t *wcsncat(wchar_t *<[s1]>, const wchar_t *<[s2]>, size_t <[n]>); |
| |
| TRAD_SYNOPSIS |
| wchar_t *wcsncat(<[s1]>, <[s2]>, <[n]> |
| wchar_t *<[s1]>; |
| const wchar_t *<[s2]>; |
| size_t <[n]>; |
| |
| DESCRIPTION |
| The <<wcsncat>> function appends 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 <[s2]> to the end of |
| the wide-character string pointed to by <[s1]>. The initial |
| wide-character code of <[s2]> overwrites the null wide-character code |
| at the end of <[s1]>. |
| A terminating null wide-character code is always appended to the result. |
| If copying takes place between objects that overlap, the behaviour is |
| undefined. |
| |
| RETURNS |
| The <<wcsncat>> function returns <[s1]>; no return value is reserved to |
| indicate an error. |
| |
| PORTABILITY |
| <<wcsncat>> is ISO/IEC 9899/AMD1:1995 (ISO C). |
| |
| No supporting OS subroutines are required. |
