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.
