identifying a raise_closure from C

[Bernard James POPE]

Hi all,

In C, I have an StgClosure pointer, pointing to a THUNK.

I would like to know whether this particular THUNK is a raise_closure,
(as built by raisezh_fast() in rts/Exception.hc).

Is there any identifying information I can use to tell definitely whether
this THUNK is a raise_closure? Perhaps the stg_raise_info info table
has enough information?

Thanks heaps,
Bernie.
