get the class of an instance

[Elias Athanasopoulos]

Hello!

I want to get the class of an object through the Ruby C API.
Actually, I want what foo.class does.

I tried:

foo = STR2CSTR(rb_iv_get(self, "@class"));

but it doesn't work.

I also tried:

foo = rb_obj_as_string(rb_obj_class(self));

which it seems to work, but it produces a strange output:

% ruby gen.rb
gen.rb:11: warning:

Foo

(Notice the '\n's after warning

Is there another better way? (Okay I can replace '\n's but it
seems to me that I'm following the wrong way).

Regards,

VALUE foo;
char *name;

name = rb_class2name(CLASS_OF(foo));

VALUE foo;
char *name;

name = rb_class2name(CLASS_OF(foo));

That was the trick. Thanx. Apologies for my delayed answer.
