Hi Shrirang,

I am not sure if I understand you correctly, but are you trying to write 
an attributed variable handler for delayed_goals? This handler
is obsolete, as described in the section on Attributed Variable Handler 
in the User Manual:

http://eclipseclp.org/doc/userman/umsroot100.html#hevea_default1039

You should be using the suspensions handler instead.

The handler should not be working on all suspensions (delayed goals).
Rather, it should be working on suspensions that are associated with
the variable which has the attribute you are handling.

It is not clear to me if you should be writing handlers for 
suspensions/delayed goals. You will normally only do this if you are 
writing a new constraint solver:

 From your previous posts, it seems more likely that you want to write 
constraints for existing solvers; in which case you should be writing 
the constraints using facilities provided by the solver library.

Cheers,

Kish
