I think this is going to be confusing. From the man:

	The strcpy() and strncpy() functions return a pointer to the
	destination string dest.

I think it would be better to keep the same behaviour, especially since
you used the same name for your functions (which I think is sensible),
not to mention you don't use this return value in any of your calls.
(IMHO strcpy() shouldn't have had a return value and neither should your
functions, but since it does, yours should match.)
