[Jikesrvm-researchers] Access Java Objects in sys.C

[Wei H. <hua...@gm...>]

Hello,

I want to find out object connectivity when GC is running. My approach is t=
o
create a separate pthread (in sys.C) when GC is triggered and assign it to
access object information on-the-fly. However, tracing object information i=
n
native C code seems not easy. Specifically, I need to call several RVM
functions (including getslot(), getMemoryAddress(), getObjectType(), etc).
Is there any way to call such Java methods inside sys.C? If no, is there an=
y
other solution to trace object layout  from a C function in RVM? Your help
is appreciated.

Best Regards,

-Wei
