Subject: [ruby-talk:29515] C extensions: ruby and C strings

1) Should I free string here or is it used as string buffer by Ruby ?
	
	char *cstr;
	VALUE rstr;

	rstr = rb_str_new2(cstr);
	free (cstr); // ???

2) Does cstr point to Ruby string buffer or should I free it ?

	VALUE rstr;
	char *cstr;

	cstr = rb_str2cstr (rstr, 0);
	do_something_with_const_string (cstr);
	free (cstr); // ???

3) Is RSTRING(rstr)->ptr null-terminated ?
