Not really...

In Ruby I call
rv.rPAInit { |a| Callback_fn(a) }

and use this block in my c-routines (in my dll).
And I need the block in another function!

In my wrapping-init function (in the dll, c-code)
the block is there and rb_yield does the right things.

But in another function (my thread)
rb_block_given_p
says there is no block and so I can't do rb_yield.
But I need the block in the thread...

I'v tried some things like the example in the ruby-html-docu
(the CD-Player...) but rb_block_given_p fails (in my thread).

Also:
In the c-function which wrapped rPAInit the block is there.
In my thread the block is not there - but I need the the block
in my thread. I don't know how to redirect the block...
It's all c-code
