otcl c++ variable binding.

[Karunaharan Ratnam <karu@ece.neu.edu>]

HI,

I tried to create a new variable duplicate_ in C++ and want to
bind it to duplicate_ in otcl.
I have a new class of type Classifier/MH, and set 
"Classifier/MH set duplicate_ 0" in ns-default.tcl.

In the file MH.cc, I defined the var duplicate_ as integer, and bound it by,
bind("duplicate_", &duplicate_).

But, when I try to access the variable duplicate_ in the test script,
it gave an error saying 
 can't read "duplicate_": no such variable

Any help.

Karu.
