4 
5 SYNOPSIS

10 DESCRIPTION
11 	The <<wcscpy>> function copies the wide-character string pointed to by
12 	<[s2]> (including the terminating null wide-character code) into the

14 	overlap, the behaviour is undefined.

16 RETURNS
17 	The <<wcscpy>> function returns <[s1]>; no return value is reserved to
18 	indicate an error.
19 
20 PORTABILITY
21 <<wcscpy>> is ISO/IEC 9899/AMD1:1995 (ISO C).
