OK... how about the previous version of strscpy() from Linux.

static size_t strscpy(char *dest, const char *src, size_t size)
{
	size_t len = strnlen(src, size) + 1;
	if (len > size) {
		if (size)
			dest[0] = '\0';
		return 0;
	}
	memcpy(dest, src, len);
	return len;
}

This one aborts on too long source. Would it match the NetBSD kernel needs?
