ANSI_SYNOPSIS
|
||
|
|
#include <wchar.h>
|
||
|
|
wchar_t *wcscat(wchar_t *__restrict <[s1]>,
|
||
|
|
const wchar_t *__restrict <[s2]>);
|
||
|
|
|
||
|
|
TRAD_SYNOPSIS
|
||
|
|
wchar_t *wcscat(<[s1]>, <[s2]>
|
||
|
|
wchar_t *__restrict <[s1]>;
|
||
|
|
const wchar_t *__restrict <[s2]>;
|
||
|
|
|
||
|
|
DESCRIPTION
|
||
|
|
The <<wcscat>> function appends a copy of the wide-character string
|
||
|
|
pointed to by <[s2]> (including the terminating null wide-character
|
||
|
|
code) 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]>. If copying takes place between
|
||
|
|
objects that overlap, the behaviour is undefined.
|
||
|
|
|
||
|
|
RETURNS
|
||
|
|
The <<wcscat>> function returns <[s1]>;
|
||
|
|
no return value is reserved to indicate an error.
|
||
|
|
|
||
|
|
PORTABILITY
|
||
|
|
<<wcscat>> is ISO/IEC 9899/AMD1:1995 (ISO C).
|
||
|
|
|
||
|
|
No supporting OS subroutines are required.
