FUNCTION
|
|
<<wcpcpy>>---copy a wide-character string returning a pointer to its end
|
|
|
|
ANSI_SYNOPSIS
|
|
#include <wchar.h>
|
|
wchar_t *wcpcpy(wchar_t *<[s1]>, const wchar_t *,<[s2]>);
|
|
|
|
TRAD_SYNOPSIS
|
|
wchar_t *wcpcpy(<[s1]>, <[s2]>
|
|
wchar_t *<[s1]>;
|
|
const wchar_t *<[s2]>;
|
|
|
|
DESCRIPTION
|
|
The <<wcpcpy>> function copies the wide-character string pointed to by
|
|
<[s2]> (including the terminating null wide-character code) into the
|
|
array pointed to by <[s1]>. If copying takes place between objects that
|
|
overlap, the behaviour is undefined.
|
|
|
|
RETURNS
|
|
This function returns a pointer to the end of the destination string,
|
|
thus pointing to the trailing '\0'.
|
|
|
|
PORTABILITY
|
|
<<wcpcpy>> is a GNU extension.
|
|
|
|
No supporting OS subroutines are required.
