Simple extension question

[Mark Probert]

Hi ..

What is the easy way of clearing an array in an extension?

ie Given

VALUE t_init(VALUE self)
{
VALUE foo;

foo = rb_ary_new();
rb_iv_set(self, "@foo", foo);
}

How do I do the equivalent of "foo.clear" ?

Thanks,

rb_ary_clear(foo);

Tricky, eh? :-P

For a complete list of methods, take a look at intern.h.

Thanks, Dan. I knew it was something trivial. I haven't done any extension
coding for some time and forgot about 'intern.h'.
